Milton Glaser was a Lettera user. For this compilation with recordings of works by Beethoven, he* opted for Walter Haettenschweiler’s Strada. The bold condensed face with all weight allocated to the tops and bottoms was included in the third volume of the Swiss alphabet book series, published by Niggli in 1967. The massive overshoot in round letterforms (see “oven”) can be found back in the original.
*) That’s assuming Glaser handled the typography himself, in addition to providing the cover art. Maybe it was an uncredited typographer at Columbia Records.
