This painting was an unfinished work of Frida Kahlo. She started painting it in 1940s and continued to work on it until she died in 1954. She has consistently working on this painting during her stay in hospital in 1950. After her older sister Matilde passed away in 1951, she stopped working on this one and started on another painting called "Portrait of My Father".
This painting is a family tree representation. On the top are her grandparents and in the center are her parents. In the bottom Frida stands at the center and her two sisters, Matilde and Adriana, stand right next to her. On her left side is her younger sister Cristina. It is still a mystery who the three unfinished figures are. Some said two of them are Cristina's children, Isolda and Antonio. But others stated they are Frida's two half-sisters, Maria Luisa and Margarita, from her father's previous marriage. Another small sketchy figure are not really identifiable but maybe Frida's older brother who survived only a few days after his birth. The fetus by Frida might be the children she lost due to miscarriage.
