American prints at the British Museum

Still jet-lagged, and shivering after leaving Uruguay's radiant sun, I went to London for a seminar this weekend. After spending two days in a conference room, down in a lightless, airless basement, I barely had time to rush to the nearby British Museum to soak up some art before hopping back to Paris via the Eurostar.
A major event at the British Museum, an exhibition of 20th century American prints had crowds packing the rooms of the usually empty Prints And Drawings department. The art is breathtaking. Here's a small sample, including a detail from George Bellows's iconic boxing scene, a beautiful Colored Girl, and Hopper's Night on the El train.

And here's a little quiz game... Can anyone guess what famous American artist, as a very young man, drew this bucolic scene with a faceless little girl sitting atop the hay? Enter your submissions in the Comments section...
