This Superman Action Hero Water Gun was made by Durham Industries and, though the card is undated, I’d guess that it was on the racks at Kmart in the mid to late 1970s. Standing about 5″ high, this squirt gun is shaped like Superman. Pull the trigger and the water comes out of Superman’s mouth, which is really bad behavior for a superhero. This example is imprinted with Kmart pricing information, because Kmart used to be one of the largest toy buyers in the United States and could demand its vendors price their products. There is some really unfortunate positioning of the Superman squirt gun and Batman’s rear end on the card art, and the horrified expression on Batman’s face makes this piece especially hilarious.
Durham also made a Batman squirt gun in a similar style.
The card is blank on the back.
