The “1919” armchair, named after the year in which it was designed, is actually archived under the code “128”. It is thought that it was custom-designed by Renzo Frau for Filiberto Ludovico of Savoy, Duke of Pistoia. Despite being commissioned by a specific customer, it became one of Poltrona Frau’s first and biggest public successes. Each “1919” armchair is numbered.
