The present portrait bust may be based on an oil portrait of the young man by Stepan Shchukin.
As is typical at Sèvres, the incised marks give a very complete history of the present model, a diplomatic gift from Napoléon I: The incised A.B. are the initials of the sculptor Aléxandre Brachard fils (1775-1843). The J.B. are those of his brother, Jean-Charles-Nicolas Brachard, l'aîné (1766-1746). Active at Sèvres as a sculptor on and off from 1795 until his retirement many years later, he will have overseen the production of the present portrait. 1 m 8 or 1 March 1808 is the date of firing.
The No.1 notation is intriguing in that a portrait of Alexander I of Russia was known to have been a diplomatic gift from Napoléon I of France to the Tsar. See M. Ch.-E. de Ujfalvy-Bourdon, Les Biscuits de Porcelaine, Paris, 1893, pp. 9-10 where the author reproduces relevent entries from the factory's records. In a notation that post dates the previous entry of 16 February 1808 is written a listing of S©vres porcelaine sent to Russia by the French emperor, including Buste de l'empereur Alexandre, 60 francs. Given the numbering on the present bust and a firing date of March 1808, could it be that this very example was the gift?
