This is a 494-piece wooden jigsaw puzzle of Albert Bierstadt's 1864 masterpiece, Valley of the Yosemite. Our puzzle has Yosemite-themed whimsy pieces, a tidy but irregular edge, and rectangular-ish pieces with earlet connectors. Whimsies by Kathryn Flocken and puzzle design by Tara Flannery. The puzzle's difficulty is harder than average. All of our puzzles are laser-cut from 1/4" wood. Made in the USA (in fact, just a few hours drive from Yosemite!). Packaged in our standard unfinished pine wood box.
