Knickerbocker Photo (Update)

But let me declare my bias from the outset: I am not convinced the stereoview depicts “six learned gents,” let alone the Knickerbocker Club.

All probabilities have a margin of error. Most people are aware of this when they see political polling: when one candidate leads in the polls 51-49, but the polling organization discloses a 3% margin of error, it is understood that the race is a statistical tie.

What we need to know is the margin of error for the facial recognition software used. The problem is that the software maker determines a margin of error using the same photographic process and type (say, a mug shot or passport photograph), similar lighting, contemporaneous images, etc. And what we have here are different photographic processes (salt, albumen, and, I believe, a silver gelatin copy photograph), with very different lighting (outdoor versus studio), taken many years apart, with limited visual information (these are group photographs taken from a distance where the ears are not visible, etc.), and where the original poster has altered the shadows in the photographs using another software program prior to analysis.

To give you some idea of how high the margin of error may be in this case, consider that a Google search shows estimates for facial recognition for African-American women may be higher than 35%. And that is with all the commonalities and without the difficulties cited above. I would be stunned if the margin of error here were not much higher. One can’t speak of meaningful probabilities in the presence of such a high margin of error. You’re asking the software to do something for which it was not designed and not tested.

Paul- I didn't even consider this stereoview being a silver gelatin print. It may well be. I can't tell from the posted images. That would push it into the late 1870s, at the earliest?

Sorry for the confusion, Gary—I wasn’t clear. I believe the stereoview is albumen. The final image above, depicting a man who appears to have just removed his cap, is—I believe—a later silver gelatin copy photograph of an 1859 print. I may be mistaken; doing this from memory, which gets increasingly unreliable.

Edited to add: the person I am referring to has been identified by some sources to be Charles Schuyler De Bost, but I think even that identification is tentative. The image of De Bost was taken from a “photostat copy” in the collection of the New York Public Library after the original was either lost or stolen. Suffice it to say that working from a photostat copy of an original albumen photograph introduces error.

SteveS, you might want to try contacting Mark Fimoff from SABR for his opinion. He is a facial recognition expert.

Thank you all for your opinions. I find it really interesting that some people can look at it and see the resemblances immediately, while others don't see anything. As for provenance, while it would be great to know more about this photo's history, I have learned from this forum that provenance is not everything. There is a fascinating thread from several years back regarding the 1847 daguerreotype purported to depict the Knickerbockers. It was given to the Hall of Fame by Alexander Cartwright's grandson. They used it to design his plaque. It's been pictured in books and TV shows, including by some of baseball's most noted historians. Rock-solid provenance. But one of SABR's experts had questions, and wrote a lengthy analysis about how the photograph does not depict the people suggested, despite the fact that it was kept within Cartwright's family. The owner wrote a very passionate defense. Both were supported by facial-recognition experts who had diametrically-opposed opinions. In the end, it's up to the viewer to decide.

As for facial-recognition software, I merely pointed out the results that I got (and I need to correct that it was 82%-97%). I do not put full credence in that, and would never claim that it proves anything conclusively one way or the other.

As for the similarities I see, I will try to summarize some of them here. For Avery, the slanted jawline. For Adams, the eyelids/droopy eye and open mouth (all of which can be seen in both of the comparisons I posted of him). For Curry, the severely bagged eyes and open mouth. For De Bost, the hairline and face shape. For Niebuhr, the hairstyle, including the parts combed forward. For Birney, the face shape and ear placement. Please note that this is just a very cursory summary of just a few of the unique features that stand out. For each of them, the eyes, noses, mouths, and ears all line up in terms of size, shape, and placement.

And to Gary, this stereoview is an albumen. I believe that Sphere was referring to the photo taken in 1859, which is a copy (I am not sure whether the original still exists).

Finally, I am not sure whether this photo will ever be proven to be Knickerbockers with 100% certainty to everyone's satisfaction. As I pointed out above, rock-solid provenance is not what it's cracked up to be. I remember being at a card show at the Pomona Fairgrounds back in the '90s right after Bruce McNall bought the Wagner and PSA made it its first slab. It was displayed by the front door with a huge security guard standing next to it. I took one look, and within half a second knew that it was trimmed. If you've never seen it in person, it's blatantly obvious. I told anyone who would listen, and from that moment forward have never trusted the grading companies (who continue to have issues slabbing iffy cards). Yet that Wagner has been sold and resold since then. For record amounts, despite the full knowledge now that it is indeed altered and not in the condition claimed. My point is that knowledgeable and well-meaning people can look at the same thing and see it differently. I believe that this photo depicts Knickerbockers, and others on and off this forum agree with me. Others on and off this forum disagree with me. If I decide to keep it, that's up to me. If I decide to sell it or donate it, it would be up to the other person or entity to decide whether it's worth that investment. In any event, I will continue to do research to try and find more convincing evidence, and maybe find a trusted expert who can determine with certainty the age of the photo and whether it has been made into a stereoview from an earlier image. But I know that no matter how convinced I and others are, there will always be people who disagree. That's human nature for you.

Sphere, thank you for your clarification! You posted it while I was writing my lengthy post above, and I didn't notice until after I posted it.

Rob, Mark has seen the images. Unfortunately, they were the earlier ones which were much less clear and my identifications were not correct. I am hesitant to send them to him again with the clearer images and much more confident IDs, as I know that he's a very busy man and I don't want to be a bother.

I know nothing about the subject but sure am enjoying this thread.

For the next to nothing it is worth the photos don't look like the same people to me.

[SteveS]

Thank you, bnorth! It's always fun to discuss baseball and its history and memorabilia.

Gary, I did not notice above that you asked to see the back of the stereoview. Here it is (and it's not the larger Imperial size).
