Letter-Form, by L. Epstein. Folio folder measuring 50cm containg four typographic mazes of various sizes, n.p., n.d. [but obviousy privately printed, mid-1970s.]
Four Letraset mazes, the riddle of which is to travel "alphabetically" to a define point. Not as easy as it sounds - a sort of typographic crazy golf. A fine copy, tissue-guarded.
