Exactly what it sounds like. Take a look.
This signed charcoal and white chalk drawing was executed on 19x25 inches of grey paper. The picture above has been cropped slightly to remove the margin of bare paper left by the masking tape. More about this drawing here, and the resultant painting here and here.
Now, although eBay for some reason wanted to put my drawing into the "Developmental Baby Toys" category, I don't recommend that you purchase it for your toddler.
The auction ends on June 11th. Cheers, party people!
