Heritage Galleries has just posted on eBay (and their web site) new listings for all sorts of interesting comic/fantasy/illustration original art. A little pricier than your typical screenprint - but these are one-of-a-kind artist originals, not multiples.
Like that Vampirella oil (left) by Sanjulian.
Yes, real drawings and paintings. If you're like me, it's enough to check 'em out without having to mortgage the house (again) to actually have the winning bid.
Bids can be placed at any time online and live August 7-8.
