Dynamism of a Dog on a Leash, 1912
Oil on canvas
Albright-Knox Art Gallery, Buffalo, N.Y.
Steve Martin makes reference to this painting in his new memoir, Born Standing Up, an excerpt from which can be read online at the Smithsonian magazine website. (But try hard not to read the comments until the very end.) And make sure you watch the video of Martin's breakthrough performance on The Tonight Show. It's a stitch, especially the part where Martin talks about how some of the acts who play Vegas get paid a lot of money.
