Details 343 came from Lucas Cranach the Elder's Venus (1532), one of the flagrantly saucy nudes painted in the artist's old age. It hangs in the Stadel Institute in Frankfurt.
The first three correct entries came from David Jeffroy of Knowle, Bristol; Elspeth Graham-Tooll of Edinburgh EH1, and Sally Ware of Stroud, Glos. Congratulations to all.
Each will, in due course, receive a bottle of champagne, as will the winners of this week's competition. Answers, on a postcard (to arrive by Wed 23 Jul, please), to: DETAILS 345, Independent on Sunday, 1 Canada Square, London E14 5DL.
