This comic first appeared in my series "Who Needs Art?" for Medium.com - check out the original post for some of the history behind the feud between Tatlin and Malevich. This comic could also be called "Constructivist vs. Suprematist." I think Constructivism was a fascinating movement, but I'm partial to the geometric energy of Suprematism.
The last panel alludes to the Russian artists who combined the language of both movements in their work. One of my favorite examples is A Story of Two Squares by El Lissitzky, a remarkable children's book that advocates Constructivist principles of cultural progress through Suprematist shapes and colors.
