Finished Puzzle Size: 19¼ x 26⅝ in. The puzzle in this box is a mystery. Don’t even try to guess what it is. You will only be able to unlock its secret by putting it together. With more than 150 Boardwalk titles to choose from, there’s no telling which tantalizing title you will get. One thing we can guarantee is that you’ll have a magical time seeing the image come alive. Boardwalk Mystery Puzzles come with a special sealed black envelope. Inside the envelope is a color print of the image. So, if you absolutely must cheat, we’ve made it pretty easy. But we don’t recommend it, because as our mothers told us “Cheaters never prosper.”
