A few weeks ago we saw one of these putative death masks for sale in an antiques centre.
L'Inconnue de la Seine (English: The Unknown Woman of the Seine) was an unidentified young woman whose putative death mask became a popular fixture on the walls of artists' homes after 1900. Her visage inspired numerous literary works. In the United States, the mask is also known as La Belle Italienne.
The one we saw wasn't expensive but it's a morbid item to stick on the wall. A talking point perhaps, but still morbid.
