SNIPED BY THE OP...But, For whatever reason, Topps used the same image for both the 65 and 68 Mays. So it would not be a stretch that Topps may have used an image from a 64 AS game on the 70 card for Clemente. Good job picking up on the home uniform...for me looking at the crowd in the upper deck in LF would make me think that it was a big game of sorts (an AS game). Below is a link to an image from the 64 AS game...uniform looks the same(including the long sleeves in July)...good call!
