This is a Marvel Characters Supercase from 1977. These cases were designed to fit LP records or as a carrying case for you action figures. This case has great graphics of the Batman characters on one side and Superman, Supergirl and Wonder Woman on the other. The case is in great shape except for the vinyl splitting on the inside of the top were the hinge is. This is the larger of the two Supercases that were made. This one is about 12 x 12 inches.
