CNN interviews Ebay artist.

"I sold my first painting on eBay for $4.75," Jeff says. "On eBay, you don't have to have a lot of money to own original artwork. There are bidders who will get onto the site and bid on every single painting I put up. And sometimes the result is the joy of the lower-end buyer, folks who are thrilled when no one outbids them. They tell me they can't believe they've got a painting they wanted."
