I'm looking for the name of a font which was quite commonly used on storefronts in France during the late 70s / early 80s (I guess). I'm also interested in some history and/or trivia about this font if you have some.
Here is a legacy exemple I've found recently:
And the subtitle of this 1983 printed document found on Wikipedia show the same font, or at least the same style. ("Grand Réseau Sud 5e 6e 14e")
I got no success with the WhatTheFont research engine.
Thanks for your help!
