The official KISS/Aucoin Accordion Fold-Out Photo Set from 1978. Set of 8 photos each connected by perforated joints that were meant to be pulled apart into 8 separate photos.
An odd item - people speculate it was part of a press kit or KISS Army Kit, but it was a stand-alone mail order-only merchandised item. Never sold in stores, so that's why you don't see too many around and almost never intact.
Each panel is 7 x 10 inches making the total, open item 56 inches x 10 inches - that's over 4.5 feet wide!
Images are of exact item being sold.
9.5 out of 10 condition.
