Here is a pre-owned puzzle made by TDC Games World's Most Difficult Jigsaw Puzzle: "CATS"  500 pieces; good condition.  15" square"   Ages 12+ Complete  This 15" square, 500 piece puzzle bears the same picture on both the front and the back.  But one side has been turned 90 degrees making it very challenging to see which side is up. Diabolically, each piece is identically cut from both sides as well.  so even an expert puzzler won't be able to tell one side, or one piece from the other.  Puzzle piece rectangle.

 Proceeds will benefit church missions.  I assume that all pieces are included but can give no absolute guarantee.
