This puzzle (artwork by Isabelle Vandeplassche) is still sealed in it's box, has never been opened or assembled, and IF there are any pieces missing it is due to manufacturer oversight. I'm pretty sure this came from Anthropologie although there's nothing on the box that indicates that. The following general description is from the Anthro site in regards to the other Jiggy puzzles that I do see there: Each puzzle comes with a tube of glue and a straight-edge tool that allows you to transform the completed design into a work of art for your walls. Includes one tube of puzzle glue, one straight-edge tool, and one reusable glass jar * 450 pieces * Board, glass * Imported * Small Puzzle: 16.75"L, 12.75"W ** Smoke-free, pet-friendly home ** I can usually ship same day ** Please feel free to make an offer and I will try to work with you! ** I will do bundle discounts, but it depends on the items - if the combined weight or package size exceeds Poshmark limits I simply can't ship. Please feel free to create a bundle of two or more items and hopefully we can work something out :) ** Thanks for looking!
