Last year, Valkyrie Historical Auctions, a seller of World War II memorabilia, offered a copy of this paper pamphlet attributed to the occupied Netherlands during World War II. The Dutch inscription says, "Where is the fifth pig?" over images of four stocky pigs.
Fold the paper correctly according to the instructions and a fleshy Adolf Hitler appears.
