4 Pack of kids puzzles by Chuckle & Roar.  Features a 200 piece Food spectrum, 150 piece map with dinosaurs, 100 piece fantasy with a Dragon and Wizard and Unicorn, and a 100 piece space & astronomy puzzle.  Each puzzle is bagged separately.  This pack has ALL 550 pieces, which are a bit larger than normal (for kids 6+) with a normal range of shape variation.
This puzzle has ALL its pieces.  This item has been used but is in excellent condition.  I have personally assembled & inspected the puzzle to verify this.
