mail a couple of old toothbrushes (don't worry, I ran them through the dishwasher) to this artist who is creating a "Welcome Mat Smile" for the American Visionary Museum's upcoming What Makes Us Smile? exhibition — made from hundreds of recycled toothbrushes! You can have your old toothbrush become a work of art too by mailing your toothbrush to the artist. Here is the info. Smile!
