This is a very rare physical puzzle made by the founder of the International Puzzle Party, Jerry Slocum. Circa 1990s, this puzzle is a very rare find, and an amazing piece of decor and conversation. The underside of the cannon piece has some weathering to it, but the top looks almost brand new (see pictures for condition). An awesome little puzzle, with a tiny cannonball inside, this is a truly unique and must-have item for any puzzle or cannon collector!
