Suzy Frelinghuysen was one of 31 women chosen by the collector Peggy Guggenheim for her exhibition in New York after her return from wartime Europe in 1942.  It was the first all female exhibition in the US.  She wanted to highlight the contribution of women artists, often dismissed by the patriarchal mindset of the time. 

200 pieces of art and ephemera have been collected by the 31 Women Collection and were exhibited for one week in New York, then in Madrid, and now in Lisbon. The show is at MAC/CCB now through June 29th. Suzy's piece above is exhibited, Brahms Abstract, c.1945, oil and collage on masonite, 15x11".
