Called "Cakepop Sam," this is part of the "Deadly Dessert Prints" by Aaron Crawford. It is printed 8 x 10 on very nice quality paper, hand-signed by the artist, and, currently, runs at $15. This is a limited edition print, so how long they will last I could not say. If you'd like to check it out for yourself, click here. I'd also recommend checking out the rest of the site, as they have some really cool shirts, prints, original art, and accessories.
