Fun and colorful Octopus puzzle by Puzz Art.  It's shaped like an octopus, with lots of curving edge pieces, and a 3d effect from shading.  The Octopus is full of fish and sea creatures.  This fun puzzle has ALL 350 pieces, which are larger than standard, with a very wide range of shape variation, due to lots of curving edges, and a red backing color.  A super fun and enjoyable puzzle.
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.
