Futura Condenced.

Got a related image. Higer quality.

Not Futura, and not Gill Sans. I'm stumped. Futura Medium Condensed was close.

I think it’s Gill Sans Condensed, actually.

That S looks like Gill, but what about that C ?

Agenda?

Gill Sans Condensed indeed.

Thanks all and sorry for not looking appropiately before asking.
