Knickerbocker Photo (Update)

[prewarsports]

I couple of things I will point out. I have been doing photography for a very long time and could write paragraphs about stereoview photography and it's evolution but suffice it to say you have a c. 1870 stereoview on your hands with it actually in my opinion most likely dating to about 1872-75. The other thing that is not really supportive of the evidence is the age range of the men in the image, while individually some of the identifications look pretty good, some are a bit off from a cursory look. The fact that some of the men in the photo appear to be quite young (maybe 30 years old) while others appear to be much older (perhaps in their 60's) combined with the vintage of the photo would be problematic for your assessment as a Knickerbocker image when coupled with the early 1870's date. Just my two cents.
