Four previously unknown watercolours by Otto Dix have been discovered in Bavaria. They were painted using mixed techniques, watercolours worked over with ink and coloured and black pencils.
Otto Dix was a German expressionist painter, and the new works are thought to have been painted during the 1920s. He is famous for painting the uglier sides of society, and particularly for his nightmarish impressions of the First World War.
The works will be on display later this year.
