1889 Ny Giant Team Photo Glass Slide
 

I recently purchased a glass slide of the League Champions photo for the 1889 Ny Giants. I've seen a little discussion on here about some of these slides for individual player photos, but after a lot of Internet research I could not find anything online about this specific slide. I'm trying to figure out when it was produced and in what volume (are there many of these or was this pretty rare). Any info would be greatly appreciated. See the link below for the photos.

I've never seen it before. Perhaps it's unique. It's from the early 1900s at the latest. The nice thing about glass slides and negatives is you know they are antique, because they switched from glass to plastic film in the 1920s-30s. Glass = old.

It's a nice pickup and my offhand guess is it's from the early 1900s, but if you research it and find it's from the 1800s, it would be a great pick up.
