To celebrate the 50th anniversary of the Apollo 11 moon landing, Four Point created their 1000 piece, circular Moon Puzzle featuring the near side of the Moon in incredible detail. The image, courtesy of NASA, is the clearest image of the Moon to date and shows even the tiniest of craters in stunning clarity. With a diameter of 26.5-inches, this puzzle gets a 4.5 out of 5 on the difficulty scale.
