WAIT, I FOUND ONE!


In 1955, Quaker Cereals including Puffed Rice and Puffed Wheat offered a "real deed of ownership to 1 square inch of land in Yukon Gold Rush Country!" The prize was part of cross promotion with the radio show Sergeant Preston of the Yukon. "Just sign your name to deed... and become owner of property in famous Gold Rush country!"
