This is such a ridiculously posed card. It’s designed to show the Braves great catcher of the 1950s, Del Crandall, giving some type of instruction to their next great catcher, Joe Torre. Torre is clearly considering his advice while staring at his mitt.
I have no doubt that Crandall had valuable knowledge ready to pass to the young Torre, but the idea that Torre was confused about something to do with his mitt is just absurd. He was, after all, the best rookie in baseball in 1961.
Of course, ridiculous or not, I love this card.
