The number of plaster impressions made on the corpse is controversial, especially because they did not survive. Antommarchi owned a plaster directly molded from an indisputable original. In 1833 he publishes the mask after signing it.
On November 7 in Paris (Hôtel Drouot), Coutau-Bégarie sells a wax version unique of its kind of the death mask of Napoléon, lot 294 estimated € 150K.
This piece made circa 1830 was signed by Antommarchi. According to a family tradition evidenced by documents that were lost in the early twentieth century, it was provided directly by Antommarchi to Noverraz.
The face has been encrusted with a fairly complete hair system 3 to 8 mm long. The DNA analysis formally attributes these hairs to the Bonaparte family. Noverraz had cut Napoleon's hair and shaved his beard during the mortuary toilet and stated to have preserved some of them. There is no doubt that these relics are made from Napoléon's hair entrusted by Noverraz to Antommarchi for this realization. A piece of cloth that remains on the neck could come from a coat of the emperor.
