Bazooka Joe Comic Cards 1972

In 1972, Topps began a series of standard size trading cards that came with large chunks of bubble gum along with a redeemable wrapper. Included with each package were two trading cards. The cards were not numbered but the backs formed four different puzzles and came in two variations, one with grey cardstock and one with white cardstock. There were 66 different cards. These cards and puzzles would run in several variations through 1979.
