Read the excerpt from Frida Kahlo by Hedda Garza.

Then she turned to the mirror on her canopy and painted the first of many self-portraits, a gift for Alex Gómez, who was still avoiding her. She completed the portrait in time for the first anniversary of the bus accident. It portrayed her in perfect health and wearing an elegant red velvet dress. . . . "Put it in a low place so that you can see it as if you are looking at me,” she wrote in her note accompanying the portrait.

The friendship between Kahlo and Gómez resumed, but their romance was apparently dead. In March 1927, Gómez, now studying law, left for a work-study program in Germany, telling Kahlo he would return in July. As he was about to depart, he claimed falsely that an aunt was having surgery and he had to rush off to help her, avoiding a personal farewell at Kahlo’s bedside.
