That's fine and dandy, but at the end of the day he copied someone else's composition, their art, claimed it as his own and never bothered to mention/credit the artists he stole from as "his" art was and continues to be hung in prominent museums around the world. Seeing those panels recreated in a different medium, in the large format they are presented in, IS interesting and thought provoking. And that is the tragedy, as well.
Screw him, honestly. He deserves any derision he gets.
I have a useless art degree from a prominent university so I am an expert.
