An article by Stella Mary Pearce on how costume evidence exposes a forged Italian Renaissance painting, the Portrait Group in the National Gallery, London, once taken for a 15th-century work and possibly linked to the Montefeltro family. She argues that the sleeves, caps, bonnet, gloves and checker-pattern trim are misunderstood copies of 1490s fashion, and that they instead reflect 1913 fashions influenced by Jugendstil and Leon Bakst's gowns for Paris couture. The article is illustrated with plates of Carpaccio, Crivelli and Klimt paintings and with Gazette du Bon Ton fashion plates.
