Francis Picabia, a good friend of Marcel Duchamp who would have been the cold-veined hitman if Dada had been an organized crime organization, is best known for his allusively erotic faux-machinic diagrams. He once splattered an inkblot on a piece of paper and called it a portrait of the Virgin Mary. But as the blog "Adventures in the Print Trade" points out, he also had a reasonable career etching fuzzy naturalistic prints of boats, people and landscapes, in the style of Pisarro and Cezanne: "It’s as if Damian Hirst had begun as a Pre-Raphaelite, or Marina Abramovic were to suddenly unveil a hidden stash of genteel watercolours of flowers in vases."

Just one more reminder that avant-gardistes weren’t avant-gardistes because they couldn’t draw trees right.
