The other day I found a Coloring Book/Sticker Book that looks like it came from Pizza Hut. It was in perfect shape, so I snatched it up for $5. I love this art style, It reminds me of the other pocket books, like the Care Bears Garden Book.
I'm going to be scanning it in and making some High Quality graphics as well. I'm thinking a Pizza theme is in order.
