Twelve prints from the "Mascherata alla Greca" (Greek style masquerade) series by Ennemond Alexandre Petitot

It's a nineteenth-century reprint: the original edition was on straw paper. In 1771 Benigno Bossi etched the Petitot series of nine sanguines, owned by Du Tillot, entitled "Mascarade à la Grecque", completing the print run in November, just before the minister, who fell out of favor, left Colorno.
