Mexican artist Frida Kahlo is known for her colorful self-portraits.

An exhibit of her personal photographs, discovered more than half a century after her death, offers insight into her life. But it also raises some questions.

Frida Kahlo, who died in 1954, is one of Mexico's best-known artists. She was the subject of the 2002 movie "Frida" starring Salma Hayek.

The 240 photos in the new exhibit at Artisphere in Arlington, Virginia, were chosen from more than 6,000 discovered recently in the home Kahlo shared with her husband, Diego Rivera.

Only four are known to have been taken by the artist herself, including one of her dog and a portrait of her nephew.

?She actually wrote on the back of the photo: Frida Kahlo,? says Cynthia Connolly, Artisphere?s visual arts curator.

?It?s almost like a horse-drawn cart, where the horse is topsy-turvy and the person is on the ground," she says. "It makes me wonder if she is depicting her own accident in some Mexican toys.?

Frida?s bus accident, dramatized in the movie "Frida," caused severe injuries to her spine.

In the exhibit, several images show her in a hospital.  

?You can tell she had pain most of her life," Connolly says. "She was continually having surgeries to try and relieve her of that pain."

Other photos show family and friends, including photographer Nickolas Muray.

"What you see in his studio is very interesting, because with the magnifying glass, you can actually see there's a portrait of Frida Kahlo on the wall," Connolly says.

There are also self-portraits of her father, who was a professional photographer.

?There are about 20 self-portraits of her father, very formal photographs," Connolly says. "They lead us to believe that possibly her father was a great influence on her art.?

Frida collected photographs by other artists such as Man Ray.  

?When you look through this exhibit, I wonder what she saved and why she saved it. Was she planning on using it for a painting

We may never know.
