Seen in the display is half a pimple ball which was used in the game known as halfball. The game was played all around Philadelphia. All you needed was a half ball and a broom handle, a pitcher, batter and catcher. Alas, the game was not invented in Philadelphia, but originated in the south at the beginning of the 20th century in Savannah. I played it in 1956 and was the pitcher for both teams who played the game for as much as $100, which was a lot of money at that time. They payed me $10 to pitch fairly to both teams. I was known as Fair Ball Lefty, I guess because I only had a left arm. I would supply halfballs, which I would get off the roofs or in the sewers and drain spouts.
