Shown in PLINC’s Psychedelitypes (1968) as Pyschedelitype 57362 (caps only) and 57363 (with lowercase), and then in Alphabet Thesaurus, Vol. 3 and One Line Manual (1971) as Davison Arabesque. Appears to include two forms of ‘R’ (with/without hook) and ‘E’ (with/without longer middle bar).
A very similar caps-only design is shown in the 1976 Lettergraphics catalog as Vigus (solid) with Unicorn Open (outlined). A Filmomaster catalog additionally lists Vivid (outlined shaded) and Vapor (filled with pattern of curved lines). Other phototype catalogs show Vigus as Unicorn Black. The ‘Q’ has a centered tail, which may have been an alternate in PLINC’s version.
