Portrait of Mary Louise McBride (Mrs Homer Saint-Gaudens), 1929. Louis Buisseret (Belgian, 1888-1956). Oil on canvas.

The sitter, Mary Louise McBride, was the second wife of the critic, stage director and writer Homer Saint-Gaudens;  they were married in Pittsburgh in 1929, the year this portrait was painted, so it may be considered as a twentieth-century contribution to the long tradition of marriage portraits.
