M: Hi, Mary. I see you and your friends have been decorating the dormitory lounge.
W: Hi, Jack. The walls look so stark and dreary, so we decided to cover them with prints and posters.
M: I like this one. Did you buy it on campus?
W: No, I bought it at the Museum of Modern Art in New York City. The Art History Department recently sponsored a special museum tour there.
M: Is this a reproduction of something in the museum’s collection?
W: Yes. It’s a print of a painting by George O’Keefe called “Lake George window”.
M: It looks more like a photograph. The details are so accurate and realistic.
W: I thought the same thing when I first saw the painting hanging in the museum. But the Art History teacher pointed out how the painting is in fact very stylized.
M: What do you mean?
W: First, by choosing a front view of the window, O’Keefe was able to present a symmetrical image and eliminate any hint of three-dimensionality.
M: It does look almost flat. The open shutters seem to have no depth at all.
W: To emphasize that two-dimensional look, O’Keefe also eliminated details of texture, the shutters, for example.
M: It sounds as though you learned a lot on that trip. Is the Art History Department planning another museum tour?
W: Yes. The next one is a special exhibit of European painters at the Museum of Fine Arts in Boston.
M: I think I’ll sign up for that one. Maybe I will come back with a print to decorate the bare walls of my dormitory lounge.
