Shown in three variants; Gothic (w/ lowercase), Caps (caps only, w/ some extending alternates, shown), and Animated (w/ lowercase and many extending/swash alternates for the caps) [PLINC 1971]. Used already in 1969.
Possibly inspired by Art Nouveau initials and vignettes (as well as type?) shown by Deberny & Cie.
