Hi, Just curious as this appears not to be an original and some kind of something. Any ideas where or what this project was supposed to be?
It looks like it was printed on cardboard.
My first thought was that it looked like one of the 1972 Topps Cloth cards that was a test issue and never actually released to the public. The ones that made their way into the public realm were in uncut sheet form so each card would have to be hand cut which could explain the oversize of the card as well as the coloring along the top and left borders.
With that said, all I could find in that set was the Clemente In Action card and not the regular card.
