A monolinear all-caps face made mostly from straight or almost straight lines. Shown by Photo-Lettering as Cavanagh Cleopatra [PLINC 1950] and later as Apache, then with bouncing baseline and ligatures, but no design credits. [PLINC 1965] Originated by John Albert Cavanagh, who showed this alphabet in his Lettering and Alphabets from 1955.
A similar or identical design is shown by Solotype as Appian (without bouncing baseline). [Solo 1992]
Edessa JNL (Jeff Levine, 2010, used for sample) is “a Greek-styled alphabet found in an old book used by sign painters” – probably Cavanagh’s book.
