The card fronts feature a piece of painted artwork surrounded by a white border, with no text. The card backs give the set name and card number, followed by a large block of text and the Mister Softee logo and copyright info at the bottom.
This card set tells a brief science fiction story starring the hero Captain Chapel. Apparently this was meant to be one of a series of similar sets detailing further adventures, 'Trip to the Moon' being one of many of the Adventures of the title character.
This apparently never happened, however, as this is the only set known to feature the character.
The cards were distributed one per pack of a specific type of ice cream treat sold through the Mister Softee trucks.
