A friend of mine found this seller's page on ebay:
http://shop.ebay.com/uzbek_silk_road/m.htmlIf you go to page 2 of the seller's auctions, you'll notice some familiar artwork, here's one example:

From what I can tell, someone traced over my artwork, added watercolor and then claimed it as their own. Now I've seen my online comics available for download all over the net, even translated in other languages, like Spanish and Russian.
But since there's really not much a person can do about that, I'm not bothered by it. In fact, I think it actually provides me with a bit of free publicity.
What irritates me about this particular case, however, is that the auction claims that the work in question is "signed by the artist", a Russian named Popov. Using someone's artwork, coloring it and then claiming it as your own is kind of a sham, I would think.
In any case, ebay has been notified and it's wait and see for now...
I'll let you know how it develops.
As for some "real" artwork, I know it's been a while but I will be posting some new work in the coming days, promise!
Stay tuned...
EDIT: To be fair, I do give the seller the benefit of the doubt, since he or she might not be aware of what Popov is doing. But if you are going to represent an artist, maybe you should make sure he's legit.
