Three flavors, all in three weights: Envoy, Envoy Nouvel, and Envoy Biform. It’s not clear which is which. One is directly based on Peignot, one has a more conventional lowercase, and one has capitals derived from Peignot’s lowercase. [PLINC 1965] The first flavor was later offered as Peignot, and the second one as Envoy. [PLINC One Liner 1971]

Etcetera Biform is a related design.
