The Two Fridas 

Frida Kahlo had a very painful life both emotionally and physically. She had an unstable marriage in which her husband cheated on her multiple times and she returned the favor. She was deeply in love with her husband but they struggle to keep their marriage intact. She was a very successful person in the art world and her success made it seem as if to drift from her Mexican culture. In this painting it shows how in her are two people. There's the person who everyone knows as the successful artist and then there's the one whose been engraved with her Mexican culture. It also implies that Frida's husband was in love with the woman who was more connected to her Mexican heritage than the one who was a successful artist. This also confirms the possible problems they might have had in their marriage.
