A sans-serif, condensed, narrow, geometrical typeface that seems to be based on a narrow vertical rectangle used as a grid with a 7:2 ratio, perhaps.
It was used for the masthead of an architectural magazine, in 1946. Reminded me of Wim Crouwel's Hiroshima poster (1957) and I wonder if that particular typeface was in turn based on other typographic/visual trends at the time. Thank you!
