Showman Frank Hansen claimed to have a bigfoot-like creature frozen in a block of ice and was exhibiting it at carnivals throughout the Midwest. In 1968 the creature came to the attention of the cryptozoologists Ivan Sanderson and Bernard Heuvelmans, who became convinced the creature was real. Sanderson tried to get scientists interested in the "iceman," and for a brief time the Smithsonian Institution expressed interest in acquiring it. But as pressure mounted on Hansen to let scientists examine the creature, he claimed that the original creature was gone and what was now in the ice was just a replica. It has since become clear the creature was a fake all along.
