These brand new paintings are available on Ebay right now...very reasonable beginning bids, and the 2nd one is just over 3 feet tall. Click to visit the auctions.
When I really want something on ebay I use BidNapper.com, it allows you to set your maximum bid but does not place your bid until the closing minutes of the auction. This way you avoid emotional bidding, keep on budget and don't have to be around when the auction ends...and it's a free service for the first 15 days!
