vintage Longchamps matchbook

This promotional front strike matchbook for Longchamps Restaurant caught my eye with the calligraphic “L.” Upon opening the matchbox, 15 little chefs are revealed as matchsticks.

A guess is that the design is from the 1940/50s. Any additional information about the designer or other relevant info always appreciated.
