Brand: Artifact Puzzles From manufacturer: This is a 357 piece puzzle of Erin Hanson's painting, "Crystal Grove". This puzzle is one of the most difficult we make with our unique split tendril connector pieces, just a few themed whimsy pieces, and the beautiful edge that arises naturally from the piece shapes (so you cannot separate out the edge pieces!). If you are looking for a gorgeous and challenging puzzle, this one is for you. (Really hard difficulty.) NOTE: The irregular edge is not shown in the image on the box! The puzzle was designed by Tara Flannery and Jef Bambas, inspired by a tessellation by Mark Dow. Its pattern and whimsies pair well with Erin Hanson's California Impressionism art style and emphasis on movement in the landscape. Like all our puzzles, laser-cut from 1/4" thick wood. Packaged in our standard pine wood box. Made in USA. 10" by 16" Manufacturer recommended age: 15 years and up
