The Master (KEL TU 010) is a comic published in 2013 on tumblr (and later on DeviantArt) by Kelly Green.
Four phases of Dorian Gracey's portrait decaying from a handsome young dandy to a possessed skeleton.
The phases are based on the corresponding phases of the Aging Man portrait in the Walt Disney World Haunted Mansion ride, though the ride includes more than 4 phases.
“I guess you could say he aged rather un-Gracey-fully.”
“I guess you could say he aged rather un-Gracey-fully. … … … I'm really proud of that, ok?”
