In 1970 and 1971, the Topps Company issued a Scratch Off baseball game card in certain series of baseball cards. The fronts featured one player from each of the 24 teams on a red, yellow or blue background.
I guess Topps didn't have any new ideas for 1971 as that set of 24 was the same as 1970! The same players were included and the front and back of each insert was exactly the same. The only difference was the inside of the 1970 set had a white background while the 1971 set had a red background.
