I don't know on what basis Sport magazine made its all-star selections for that subset, but a lot of great players were missed.
Two such worthy selections are the subjects of my custom card additions to that issue.
Ted Williams, of course, wasn't under a Topps contract in 1960. And Roberto Clemente, whom Topps was trying to convert to "Bob" in that era, was just coming into his own as a star outfielder.
There's really nothing much to add here, I'll just post the pictures for your enjoyment.
