Elegant, artistic puzzle entitled "Still Life with Flowers" by Eeboo company.  This is a circular, round shaped puzzle!  Featuring flowers in a blue and white vase, with birds, butterflies, a frog, and other fun creatures.  A real pleasure to do!  It has ALL 500 pieces, which are slightly larger than normal with a round variation on the range of piece shapes.
This puzzle has ALL its pieces, and the included poster.  This item has been used but is in excellent condition.  I have personally assembled & inspected the puzzle to verify this.
