Gorgeous art puzzle by famous artist Charley Harper.  Entitled "Secret Sanctuary," this 500 piece puzzle features a large Egret, with many other birds, reptiles, insects, and plants.  Has a green background and ALL pieces, which are of standard size 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.
