Anyone recognize the stamping on the back of this photo? Was it some sort of giveaway? P.R. photo? I bought a small lot of signatures and photos in an auction and there are a few of these with the same stamping (Maris, Tresh, Howard, Dimaggio and Kubek). Also in the lot were some 1960 UPI Telephoto photos from the Yankees/Pirates World Series, so I suspect (hope) these are from around the same time. Any help would be much appreciated. Thanks. Rob
