L'Atmosphere Mask: RETIRED/Out-of-Stock THIS MASK IS NO LONGER AVAILABLE, even as a special order. The outer image is taken from a 19th c. engraving (unknown artist) published in Camille Flammarion's book L'Atmosphère: Météorologie Populaire ("The Atmosphere: Popular Meteorology") used to represent a medieval cosmology. The doors of the outer face are hinged, and open to reveal a starry sky flanked by musical expressions for the planets on one side and a quote from Flammarion's book on the other side. This mask isn't suitable for wearing.
