P.Unlisted - K.532.
No series, but handwritten number on the missing upper left part and with 3 claw and handwritten signatures with Foucault / Levasseur / Hulot. This type is quite simply a museum piece, as it has never been found and has never been referenced. The front of the bill also features two black diagonal cancellation lines, as intended by De Curt. The reverse shows Melon's visa with the number 111270 and the date 18 XX, the rest on the missing part.
Exceptional copy with missing upper left corner, otherwise attractive. B.
