The antique gallery in Florence in via dei Fossi was established in 1937 and developed by Piero Cei, one of the two sons of Leone, who devoted his attention almost entirely to antiques. The gallery specialises in paintings, furniture and works of art from the 15th to 19th centuries and boasts acquisitions from the most famous Italian and foreign collections and sales to prestigious museums and important private collectors. A parallel activity of the gallery is research, study and consultation as well as attention to the diffusion of art in the world and participation in art exhibitions and fairs.
