There are many others that we cannot identify, so if you can identify other artists, please contact the artist with links to the works which belong to them. Do not contact the Ebay seller, please, as that will solve nothing and only prompt them to delete all the works which may prevent artists from receiving possible compensation (if any) for the profiting of their illustrations. Only the owners of the copyrighted works may contact Ebay to get the listings removed.
