I had to be sure these were fakes. They were, but I had to be sure. And now I have confirmation from both Todd and Art that they are complete and utter forgeries.
These are the so-called sketches by Todd McFarlane and Art Adams that one Gregory Garwood sold to major comics art dealer, Mike Burkey. He paid $750 for the Art Adams piece alone. Only when Burkey paid did he realise that the receipt said "josh hoopes", the name of the comic industry's most infamous conman.
Josh Hoopes has, it seemed, moved on from trying to con the small press and wannabee creators, to aiming at a potentially more lucrative art market. And for some reason, still focusing on Art Adams' name.
