The Bowman Gum Company was a Philadelphia-based manufacturer of bubble gum and trading cards in the period surrounding World War II founded by Jacob Warren Bowman in 1927. Bowman was most notable for its baseball cards, which were highly popular in the 1940s until the brand was acquired by Topps in 1956. Bowman also produced American football and basketball cards. Nowadays, Topps commercializes a line of baseball cards under the “Bowman” name after resurrecting the brand in 1989
