This work was done by Vik Muniz. It is titled Mona Lisa (Peanut Butter and Jelly) and as you may have guessed it was made of peanut butter and jelly. Vik Muniz is a Brazilian born and, now, New York based artist who specializes in making art out of unconventional substances like garbage, flowers, and even food. His portraits are often grand in scale, taking up entire warehouses, however this one was not. His work is so interesting, because it is so different.
