The Demon by Mike Royer

I believe this piece was one that Royer did around 2011, "recreated pencils" by Kirby, that Royer traced and then inked in his 70s style. When he sold these originally at cons or privately he was quite open about this process.

Regardless if the King never touched the paper, I am thrilled to own it, Royer is a great inker on Kirby.
