The Auschwitz-Birkenau State Museum's collection of art includes work that prisoners secretly made while in Auschwitz. The museum has more than 100 portraits by Franciszek Jaźwiecki, a Polish artist and political prisoner.

His portraits portrayed prisoners of various nationalities and ages, and they shared a similar haunting quality, according to Agnieszka Sieradzka, an art historian at the museum.

"The most interesting in these portraits are eyes -- a very strange helplessness," Sieradzka says.

Sieradzka says prisoners created portraits because the "desire to have an image was very strong."

Sieradzka believes Jaźwiecki made the portraits because he was aware they would one day become important historical documents.

Almost every portrait features the subject's prisoner number, which gives historians a name to attach to the pictures.

Jaźwiecki is said to have hidden his portraits in his bed or in his clothes.

After his death in 1946, his family donated his portraits to the museum.

In addition to portraits, Jaźwiecki also made landscapes.

Through the prisoners' art, Sieradzka says, we can see the truth about Auschwitz.
