Champagne goes to Geoffrey Taunton of London for correctly identifying the bottom image of Paul Rudolph's Art and Architecture Building at Yale University as last week's odd one out. The others both had a link to a Rudolf spelt with an f. The top picture showed the Goetheanum, Dornach by Rudolf Steiner, while the middle image was of Rudolf Nureyev as Valentino. See the picture caption for Gavin Stamp's rather more creative answer.
