Dubble Bubble is a name from my childhood. The packaging had changed from the days of the 1950's ad. In my time they were end-wrapped in a yellow and red label, not packaged like their rival Bazooka Bubble Gum.
Apparently Dubble Bubble ran a series of these ads, I came across another one featuring the same style of artwork in another magazine of the same era. Actually I like the bowler-style hat and mask. Maybe an idea for my next Halloween costume!
