The signature is usually followed by a doubly encircled JBV (J&B are joined). Early on, it was doubly encircled JBV. The labels at "Rue Croix Petits Champs" began using the doubly encircled JBV (J&B joined), which remained the same on "3. rue Demours-Ternes" labels. In addition, most specimens have a number associated with them.
