Marion Greenwood was part of a family of artists, so it is no surprise that her career choice was supported by her family. The influence of Mexican muralists on her work is quite apparent. You can hear part of an interview with Greenwood via the Smithsonian’s Archive of American Art. Examples of her work can be seen at websites for the University of Arizona Museum of Art, the Fine Arts Museums of San Francisco, the Portland Art Museum, the Pennsylvania Academy of the Fine Arts, and the Met. Bonus: Alexander Calder made a brass wire portrait of Greenwood and you can see it at the MoMA’s website.
Greenwood made one post office mural: The Partnership of Man and Nature (Crossville, Tennessee).
