Ted ZanidakisThe 1939-1941 Play Ball BB cards, the Horrors of War (NS) cards
and the 1941-43 War Gum cards were printed by the same printer
in the Philadelphia area by the original Bowman Gum Co.
That is my understanding after having visited with George Moll
back in 1981. Moll's Adv. Agency was the producer of the Play
Balls and the Bowman cards. They were under contract by Warren
Bowman from the late '30s to the Mid '50s.
