Mattel Greenie Caps for toy cap guns in the 1960's including those made by Mattel and others.
A large box of the standard cap roll was a common sight on shop counters at toy shops and milk bars or corner stores in the 1950's and 1960's.
The majority of young boys of the era would have spent many hours of play time acting out cowboy and police games with caps and their toy guns.
The box is flat packed with adhesive tape in place on the end flaps for easy assembly. Review the photographs for the assembly guide.
