Hello Robert -
Unlike the most of the things you will find on baseball-reference, the early player photo ID's are very unreliable. They aren't verified, and they won't correct them even when requested to do so by multiple knowledgable people over a long period of time.
There is, to my knowledge, no verified photo of Paddy Fox. Those listed in the SABR encyclopedia include your photo and an 1894 Reading team photo. Unfortunately the ID's for the team photo are not reliable. In any case, the guy ID'd as Fox in the Reading photo is not in your photo. There is a newspaper woodcut of Fox, but I haven't seen it.
There are a number of good photos of Fisher (below are two), and he is certainly not in your photo. You are entitled to a refund. If you want supporting documentation, contact me offline.
BTW - your Carlstrom photo may very well be correct. It does resemble a newspaper half-tone image of him.
Best,
Mark
