I made a square one. I baked 3 cakes and torted them, saving 1/2 layer for the lid. I used dowels to prop the lid up so it looks open. I made the tissue out of fondant and let them dry prior to placing them under the lid.

I made a square one. The lid was cardboard that I Iced over so it would be light weight and put two toothpicks the the back of the cake just barely high enough so the lid could lean against and not slide off. Mine had eyes, peeking out of the box so the held the lid up. Good Luck!
