Unfortunately, it's not quite as easy as that. The vast, vast majority of the art I have is nameless, and most of the ones that have names have them as nearly illegible signatures. For example:

There is a signature there down in the bottom right-hand corner of his cape, but there's no way I would be able to actually determine or find the artist based on that, and that's pretty much all I have for the few that have signatures.
