"Camel Puzzle" and "Horse and Cow Puzzle."  Both of these folding puzzles were produced in 1941 (thus making them 81 years old!) by the Strombeck Press of Moline, Illinois.  Two years later, Harold Edborg (owner of the Strombeck Press) was granted patents for each puzzle, US Patent 2327876 for the Camel Puzzle and US Patent 2327875 for the Horse and Cow Puzzle.  Both of these puzzles are in MINT condition!  As such, I didn't want to unfold and try to flatten them for a photograph.  However,...

This is the first of two politics-oriented vanish puzzles produced by the now defunct www.faerietalebooks.com.  When the inner disk is rotated counterclockwise, one of the little George W. Bushes vanishes.  (Kind of after the fact, since George W. Bush had already won his second term as president of the US!  But apparently Hillary Clinton was fuming ever since the Bush family moved into HER house, which was previously occupied by Hillary and former president Bill Clinton.)  The puzzle is in ...
