Microgramma

Microgramma is a sans-serif typeface designed by Aldo Novarese and Alessandro Butti for the Nebiolo Type Foundry in 1952. It became popular for use with technical illustrations in the 1960s, and was a favourite of graphic designers by the early 1970s. Its uses range from publicity and publication design to packaging, largely because of its availability as a Letraset typeface. Early typesetters (like the AM Varityper) also incorporated it. Novarese later developed Eurostile in 1962, a successor to Microgramma that added lowercase letters, a bold condensed variant, and an ultra narrow design he called Eurostile Compact.
