Attia is French-Algerian and a lot of the work in the show dealt with themes of colonialism and European/African history.
African masks presented out of context (i.e., in a gallery setting), and two different portrayals of a monkey: European (taxidermy), and African (mask)
Injuries sustained by soldiers fighting in WWI, some of whom were European, and some of whom were recruited from colonies. Their faces before and after their scars healed.

This is from a previous show that I think included some of the same pieces. Sculptures of the scarred faces from WWI photographs which were made on commission by African wood sculptors.

Scars that might be considered deformities in one culture can be considered beautiful in another. These sculptures were based on source photos of body modification and commissioned to marble sculptors in Italy.
