Look To The Left

For some reason, this is "Mother Whistler Day."  Not Whistler's Mother, but Mother Whistler.  Though it does seem to be built around the famous painting.

The actual name of the painting is Arrangement in Grey and Black No. 1, though that's not nearly as catchy as "Whistler's Mother." The subject of the painting is artist James McNeill Whistler's actual mom, so it's a better title anyway.

It fascinates me how certain images become iconic.  They're so well known that we can't even see them for the original works they once were.

What other paintings are as well known (or as often parodied)?  I can think of three: Mona Lisa, The Last Supper (two for Leonardo!) and American Gothic.  Maybe Freedom From Want (Rockwell's Thanksgiving painting).  Sorry, I don't think The Scream or La Grande Jatte or Christina's World quite make it.
