Kigai from FA went to IndyFurCon, his first con, and while he's not a furry himself, he does traditional artwork on FA, DA and Weasyl. His artwork tends to go the distance of werewolves and horror scenes, as well as anthros.
If you know who did this, or know of where someone can try to sell these originals, PLEASE keep an eye out and let Kigai know. You can get a hold of him at the following places: FA - https://www.furaffinity.net/user/kigai/ dA - https://kigai-holt.deviantart.com/ Some of the work in that folder was commissions he was working on. Please, if you don't know what happened, spread the word to help out.
