Pininfarina Piuma Raphaels Urbinas 500th anniversary etergraph

The hidden signature. The hidden signature. Piuma is a writing instrument made entirely of wood, with a dynamic shape, reminiscent of a goose feather. In this special edition which includes an exclusive gift box, the artist's handwritten signature, almost completely hidden from the naked eye, is revealed through a polarized lens incorporated into the desk stand. The interaction becomes a game of research and surprise: just like Raphael used to do with the use of bright colors.
