Bazooka Joe was a large stick of pink American bubble gum that can still be purchased today. Around the large sticks of gum was wrapped a small comic strip starring the adventures of Bazooka Joe and his friends and advertising for cool toys and products you could purchase (although it was always American based and in U.S. dollars even in the UK!).
The gum was very chewy and you could actually get lockjaw in the school playground from trying to cram a whole bar in your mouth at once! It tasted nice though!
Bazooka Joe himself, as an advertising character, wore an eye patch lending him a very distinctive appearance.
