THE MAISON RENÉ BOIVIN ANTIQUAIRE The first pages of Françoise Cailles' book "René Boivin Joailler" reproduce pages from the stock books of antique jewellery and collectors' items offered by the firm to its customers. On discovering this mid-twentieth century case, we can suggest a neo-renaissance piece from the 1880s from this old collection. Reference: CAILLES, Françoise.
