Just recently one blogger commented on a current exhibition at the Smithsonian entitled "1934: A New Deal for Artists" (see the slide show of the exhibit). He connected the subject of a painting on the New York subway (particularly a woman applying lipstick) to dancer and choreographer Martha Graham's depiction of her life in New York where she inwardly debated daily whether to buy lunch or take public transportation home (her money granted her one wish).
The painting of the barber shop reminds me of the other day when I took my World War II veteran friend, Richard, downtown for the day. We visited a barber shop not unlike the one in the painting.
I guess some things don't change much. Thank goodness.
