Gorgeous puzzle entitled Big Cats of the Plains, by artist Cynthie Fisher, produced by Sunsout.  A stunning puzzle featuring various lions, cheetahs, leopards, and other beautiful predator animals.  Finished size of 18"x24", this puzzle has ALL 500 pieces, which are of standard size with a wide range of shape variation.  A very enjoyable puzzle for a big cat enthusiast.
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.
