DETAILS No 335

In Which painting by which painter can you find this piece of green ground?

Details 333 came from one of Magritte's best known picture-puzzles, The Human Condition (1934). It is in a French private collection.

The first three correct entries we pulled out of the hat came from: J Mawdsley of Wigan; Bernie Cunnane of London SW4; and A McKeegan of St Paul's Cray, Kent.

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 15 May) to: DETAILS 335, IoS, 1 Canada Square, London E14 5DL.
