This is a quality puzzle inside and out. It has 300 pieces in a resealable bag along with a print of the art inside the box as well. Both front and back artwork allow for a number of family or friends to work the puzzle together. You feel the difference from the box to the pieces. Expect 1-3 Hours. The size of the puzzle is large enough allowing the pieces to each have significant clues within them. Thousand faces is full of fun little details of all kinds of personalities. Turn the puzzle upside down and you'll discover even more! ...and with all Mark Ludy's art and books there is a mouse somewhere within it! Good luck!
