Not all the paintings at this exhibit are great art, but they are displayed thematically and properly explained. (Though the text is white on green, and on navel-level... Very convenient for reading. Not.). And there is Grant's 'American Gothic', 'Daughters of Revolution' and Hopper's 'Gas'.
What was perhaps missing, to my mind, was something from the rich array of photos depicting the gloomy American 1930s; Dorothy Lange, Margaret Bourke-White and their likes.
Still, it was a good exhibit and it moves on to London in a month so I'm glad I caught it in time.
