Knickerbocker Photo (Update)

[SteveS]

prewarsports, thank you for your opinions, which are appreciated and definitely worth more than two cents. It's my understanding that stereoviews from the 1860s-1870s are on colored cards with rounded corners, and usually have the photographer's/distributor's information on them. The earlier ones are white or cream-colored with squared corners and no info. As for the ages of the men, after sharpening the image and looking at each one very closely in comparison with the known photos, every facial feature is a very close match. At first I thought that the man I identify as De Bost was much older and someone else wearing glasses. But a close look shows that he is not wearing glasses and appears to be older because his eyes are mostly shut and the blur of the stereoview makes it appear that he has bags under his eyes. For what it's worth, I ran them all through two different facial-match programs and all the results showed very high positive match rates of 84%-97%. As I say, I am not sure whether the photo is an earlier one that was used to make a stereoview. In any event, thanks again, and happy collecting!
