Here is a set of fifteen sketches by Georges-François-Marie Gabriel, from the Carnavalet, said to represent "clubbists" from the Revolutionary era. They were shown to the Friends of the Carnavalet as new acquisitions in 2010, but I can't find out any more details.
The individuals depicted are perhaps stock Revolutionary types rather than real people. Maybe Gabriel used them for reference to add hats and hairstyles to his portraits.
Black crayon and wash.
