The February 1993 issue of Baseball Cards featured a section called Readers’ Choice, but I’m going to have to disagree with Eric Hoffman on this one!
The 1951 Bowman #195 Paul Richards card is the only cartoon image in the 324-card set.
I’ve read that the most common theory concerning the card was that Richards wasn’t named the manager of the Sox until the Bowman cards were nearly ready to print and because Richards retired as an MLB player in 1946 (he was a player-manager with the Buffalo Bisons of the International League from 1947-49), Bowman didn’t have any recent or suitable photos of Richards to colorize, so they had one of their artists do a last-second drawing.
