Only a couple of dozen works by Richard Wittmann appear to have survived, most of them pastels. At least one composition, possibly the most explicit, exists both as a pastel and a painting, and one of the other pastels has been squared up for a larger painting. Nearly all his known works are more or less erotic, showing Berliners enjoying mutual titillation and shared intimacy – whether this is because this was his preferred genre or just that it is these ‘secret’ works that have survived we shall probably never know.
