50 Francs - type 1864

The type 1864 fifty-franc note was among the first issues from the Banque de France to use intaglio engraving at this denomination with any real sophistication, and Pannemaker's work here was done during the height of his career as a wood engraver — an unusual choice of medium for banknote production, where steel ruled. Harang, who worked professionally under the Cabasson pseudonym, was already deeply embedded in the Banque de France's design apparatus by this point.

The three-year window of 1864–1866 is narrow, and surviving circulated examples show pronounced wear along the horizontal folds common to notes of this physical weight — the paper stock was not especially resilient under daily handling.
