It was pretty cheap and bad, and I'm not to proud of it.
It was a pizza box, and instead of flat it was situated up so you could open it. The cardboard behind the flap had a big hole. Another box was glued to it's behind with a hole in the front, so when you opened the flap on the pizza box there was a hole!
In the hole was a mask, with a paper wad inside to give the mask a round, skull look. A flashlight in the box shined upon it from under it. I still need to paint it all black so it dosen't say HOT AND READY PIZZA on the front!
I never thought to us a pizza box... That'd be a great idea. Man, nice job on that Darkshadow... Very good thinking!
