Designed by Ed Benguiat, apparently loosely modeled after Walhalla (Klinkhardt, ca. 1900), or after an untitled set of capitals shown in J.M. Bergling’s Art Alphabets and Lettering (1914). Discotheque is shown in 1971 in three weights plus Outline and Contour variants [PLINC One Liner 1971], but not yet in 1965 [PLINC 1965]. Used already in 1967.
