I wish I could find a better image online of Marsden Hartley’s 1913 painting The Warriors:

It’s the background in Alfred Steiglitz’s photograph of Duchamp’s Fountain in The Blind Man:

It’s odd that the backdrop to such a well-known photo seems to have so little existence online.

(There’s a slightly larger version in this essay by Marjorie Perloff, but that’s in black and white. She does note how similar the urinal looks to Hartley’s painting.)

(Related: Ron Silliman goes to see the Dada show in D.C. and is somewhat disappointed. He does catch what’s wrong with the show there.)
