Details 458 came from Lovis Corinth's "Self Portrait with Model" (1903). The German artist specialised in the genre "self-portrait, with a woman" - the woman normally being Charlotte Berend, Corinth's student, model, mistress, and then wife. Sometimes the form is used to present the painter as happy hubby; here, to celebrate and equate his creative and sexual powers. The artist appears as a mighty love god, a kind of Barry White figure, with the naked and anonymous woman paying homage, her face pressed on to his bared and shaggy chest, while he goes on painting. The picture is in the Kunsthaus, Zurich. The first three correct entries came from: T Jones, Edgbaston; G Wood, Bournemouth; J Pogue, London
