Well, this typeface became the typeface with the name ‹Frutiger› itself.

... And this typeface was actually designed at the end of the 1960's for the Roissy Charles de Gaulle airport signage.

You guys are on the wrong track. The CGP type was a rounded slab, not his famous sans.

Oh, of course! I mixed it up with the Roissy alphabet. Pompidou was the enquiry.

American Typewriter is the closest thing I can think of offhand.

Indeed! Sorry for the mixup.

According to Frutiger Typefaces: The Complete Works, this has been digitized by André Baldinger in 1997, but it's not http://on his website.

Interesting typeface, I’ve never seen it before. Both warm and sturdy, both feminine and masculine, both casual and formal. Now I understand why the redesign set the cat among the pigeons…

Interesting that it has a bit of the feeling of H&FJ's Archer.

FYI I have taken the liberty of pointing André this way.
Maybe he can share some more information…

It is a super-interesting typeface. The Frutiger book has a fascinating (if very short) bit about how they accounted for it being used mainly vertically, for signage.

This being said, I think Din fits the museum quite well.

Vi ringrazio molto: è che sto lavorando a un progetto in cui è molto importante la leggibilità "upside down"...
Ma come ho fatto a non accorgermi prima del lavoro di Frutiger (che pure ho visto tante volte)?
Sarà che sono un po' stanco...
