This vintage puzzle from Royal Picture Puzzle is a true collector's item! Made from heavy cardboard and interlocking pieces it depicts the beautiful theme of windmills. There is no picture cover for clues and  the puzzle would be better suited for adults, and is sure to bring hours of fun. This box has been written on and claims to be complete on February 21, 1945 and then again on May 12, 1950. There is no count of pieces on the box and I could not find any information on the puzzle.  This is  great for those who love vintage toys and hobbies. Don't miss out on the opportunity to add this rare puzzle to your collection.
