PSA/DNA has a photo authentication service. Their expert authenticators are Marshall Fogel and Henry Yee.
http://www.psadna.com/photo_authentication.chtml Beckett also the same service. Dr Cycleback is their expert authenticator. http://www.beckett.com/estore/info.a...ampaign=Photos Though I do have to say, I can't find how much it costs or how to submit pictures to Beckett. I am not employed by nor in favor of one vs. the other. Good Luck with your picture. Mark

Wow thanks a lot for the info. PSA will do it for $25. After everyone's advice and information, it seems as though there is at least a chance that it could be an original. It would cost me $75 in all to find out. Is it worthwhile to put the money into it or is a piece like this valued below $75? I'm not knowledgeable on photographs at all. Can't thank everyone enough for their help.

If all you want to know is if it is an original type 1 photo in case you want to return it, you can send it to me and I will tell you for free (maybe $5 round trip shipping). But if you want the certification to go with it, $75 total into a type 1 original photo from opening day in 1915 is worth it. You may not turn a big profit but it certainly is not too much to spend for that item assuming it is an original type 1 photo.

Silver prints
This is almost certainly a silver gelatin print. Silver is the element that reacts to light and actually holds or contains the image; gelatin is the binding agent that binds the silver to the paper. This is definitely not an albument print.
It is not worth having the photograph "authenticated" unless your authenticator can test for the presence of brightening agents in the paper, which would indicate that the paper is later (1950s). Put another way, there is no way to know if the print dates from 1915 or 1935. I do not believe there is any other scientific means for dating a silver gelatin print. I hope this helps.

If you take the photo, look at it at a sharp angle to a light like a desk lamp and see 'silvering' the photo is old. Usually appearing in dark areas, silvering is like a silver patina that gets light and dark as you change the angle of the photo to the light. Silvering is an aging process, and only appears on old photos. Silvering would show that the photo is antique.
