Dubble Yum from NP, was a bubble gum that was popular for a very short period during the 80s. Not sure how many remember this chewing gum that lost out to Bigfun that became a huge hit. Dubble yum inside collectable wrappers had scientific titbit information as compared to Bigfun that had puzzles and cricket stars on its wrappers. Probably the reason why Dubble yum lost out.
