The Frame (painting) - by Frida Kahlo

In 1939, the Louvre bought Kahlo's "The Frame," making it the first work by a 20th-century Mexican artist to be purchased by an internationally renowned museum. Despite such an accomplishment, Kahlo was still known for most of her life, and the 20th-century, as the wife of Diego Rivera, whom she married in 1929.

In this unusual self portrait by Kahlo, she seems to be experimenting with "mixed medium". The self portrait of Frida and the blue background are painted on a sheet of aluminum while the boarder of birds and flowers is painted on the back side of a glass that lays on top of the portrait.
