"Undress" (1942), an early figurative painting by Margo Hoff was on display at the Chicago History Museum, in a show titled Big Picture: A New View of Painting in Chicago, from October 20, 2007 - August 3, 2008.
The show "offers a history of painting in the city by showcasing works ranging from the late-19th-century realist, satirical, and folk traditions to mid-20th-century expressionism and abstraction."
(Currently a photograph of the actual artwork is unavailable, but posted here is a woodblock print created by the artist, based on the painting.)
You can see a brief film clip, featuring Ms. Hoff's Chicago gallerists John Corbett and Jim Dempsey, giving an overview of the exhibition here:
Margo Hoff was the subject of a posting on the prominent gay website towleroad.com, with a brief overview of her life and career, written by Matthew Rettenmund. You can view the posting by going to https://www.towleroad.com/2008/07/winter-path.html.
Mr. Rettenmund subsequently placed a very moving follow-up posting, when Ms. Hoff passed, on his own website, which can be seen at: https://boyculture.typepad.com/boy_culture/2008/08/may-orchardwinter-path.html.
The photograph at left (from 1968) shows Ms. Hoff posing before her 3-Dimensional painting "Giant Butterfly," inspired by a visit to Southern Illinois orchards. (Repository Location: Archives of American Art, Smithsonian Institution, Washington, D.C. 20560.)
