Neither the shield held by the two putti on this mirror frame nor the monogram on the reverse, presumably the maker's mark as it was traced in wet stucco, has been indentified. The shallow relief, formed by pressing stucco into a mold, has a weak top ornament that overlaps the principal tondo molding in an uncontrolled way. The putti project at an acute angle, and the whole relief tips inward to the convex mirror. The style, especially the putti, has been associated with the workshop of Benedetto da Maiano (1442-1497), a sculptor who worked in both Florence and Siena. Mirrors like this one were produced in both centers of production during the second half of the fifteenth century, making it difficult to determine which was the source of the present example.
