Sante Pogliaghi died in 2000. Pogliaghi sold or transferred rights to build bicycles under his name in the 1980s. The difference between a Pogliaghi made under his direct supervision and one that was not is the *PSM* stamp on the seat-lug, and a serial number on the seat-lug or the head-lug. These stamps disappeared in the late 70's-early 80's. Marc Rossin had the rights first, and a number of Pogliaghis appeared with Rossin-style pantographing. By the 1990s, rights to the name had passed to the Basso brothers.
