PSA photo authentication - a suggestion

So do you think they were produced as "Cabinets" by Conlon and then used for publication, or were they mounted for some reason in the process of being used for publication? (My guess would be the former, given the stamping is on the back of the mount, not on a photo that was then mounted, but not having handled very many cabinets, thought I would throw the question out there).

Also interesting (to me at least) is that this particular image does not appear to be represented among the Conlon Archive negatives that The Sporting News purchased from Conlon. At least, it's not among those presented on the website that Rogers had made for the collection (and being that there are personal shots of unknown relatives of Conlon presented there, I kind of doubt they would have held back an image of a known player). Makes me wonder how many of Conlon's negatives were lost, stolen, sold, given away, or otherwise removed from the archive over the years before Rogers bought them.
