Listener B.J. from Jamestown, RI gave us this graphic history:

One of your panelists mentioned (on 10/15/16) that the MLB logo was based on the silhouette of Al Kaline — not! It was widely thought that the model was Twins’ slugger Harmon Killebrew (who never sought to dispel the idea.) It turns out, according to many sources, including the logo designer, Jerry Dior, that logo is not representative of any specific player. According to ESPN, this factoid was corroborated by MLB in 2009.
