This "Madonna and Child" by Sano di Pietro (1405-1481) retains its original frame carved in one with the panel. The molding is proportionally rather deep for the scale of the painting. The alternating blue and gilt blocks of the dentil that encircle the Virgin and Child like a halo of stars are due to the intervention of the restorer/faker Icilio Federico Joni, who described this panel and its companion in his biography of 1936. An identical roundel framed the "Stigmatization of Saint Francis" by Sano di Pietro, also owned by Giulio Grisaldi del Taia and then F. Mason Perkins in the early twentieth century. The companion roundel has since disappeared.
