Grant Wood, American Gothic, 1930, oil on canvas, collection of the Art Institute of Chicago. Note the interesting details: the farmer's pitchfork is mimicked on the smock of his overalls. The lace curtains in the top window have polka dots similar to those on the woman's apron. These subtle details reinforce traditional male/female roles of rural America - the lace is soft and domestic, the sharp pitchfork suggests a masculine industriousness.
