The BOWMAN Gum Co. (GUM, Inc.) issued these colorful BB cards from 1941 and into early 1942. Upon the advent of WWII, GUM, Inc. switched
to producing a colorful set of 132 cards depicting the war. The last card in this set depicts the Battle of Stalingrad (Aug 1942-Feb 1943).
Correct me if there are others, but I think this is the only major BB card set that features Joe, Dom, and Vince DiMaggio
The 1941 Play Ball set consists of 72 cards which includes 15 - HOFer's....making it one of the higher ratios of HOFers/cards in any major issue BB card set.
