French or german profile portrait from early 19th century.

The man on the small pencildrawing, measuring 8 cm x 7 cm is wearing a laurel wreath around the forehead, a sort of band from the top of his head to around his chin and most strange of all: A thin, transparent veil over the lower part of his head. Who is he and what does it all mean ? I'll gladly send photos, if you tell me to which address.
