I haven't had any luck, but have only tried twice. I have seen my work offered by other people, though. There is actually one going on now. It's a framed poster, from over 20 years ago. Way overpriced... New, it went for about $100 in that frame. Don't buy it , but here's the link, for those interested. I repeat, don't buy it... There are still galleries/frame shops selling it for about $100...
