His mural depicted "skulls topped with mortarboards peer(ing) at an open hand holding the flame of knowledge reaching out of a pile of books. The skulls represent people searching for knowledge.

The figure holds the World in its right hand; from its shoulder hangs a long sheet simple titled "News." In the far-left corner stand six skeletons donning graduating robes ... starving professors hang by their necks from the fingertips of a skeletal hand as the four horseman gallop over snakes slithering through books."
