Nina Levy is a photographer and sculptor, but she draws some awesome things, too -on napkins for her sons' lunches! I would think the boys would use school napkins to actually clean up any mess, because the ones Mom puts in their lunch boxes are works of art.
You'll find photos of many of the napkins on her blog Daily Napkins, although not all the existing photographs have been posted -yet. You can sort them and see super dogs, food items, and even particular characters. There's also a section about the family's daily life called "Napkins not for a lunchbox."
See them all at Daily Napkins. Link -Thanks, Nina!
