Gerhard Richter: Birkenau

The four paintings (Abstrakte Bilder 937/1-4) from 2014 are known as the Ausschwitz Cycle. They are based on four photographs, which prisoners took of an execution in Birkenau concentration camp in 1944 and which have preoccupied Richter for years. He photographed numerous details of these paintings and then chose 93 photos for this book.
