The Crazy Harold font set was inspired by a single analog font as reproduced in Paul E. Kennedy's "Modern Display Alphabets" (Dover, 1974).
Of course the name appealed to me, as well as the tacky retro-festive style. My font set is completely redrawn with clean edges and rounded points. I've incorporated alternate letterforms into separate fonts.
Coordinating "Flair" fonts have extra-groovy capitals!
