Grumpy is loosely based upon ITC Grouch by Herb Lubalin. Style is somewhat much heavier than Grouch, and lots of glyphs vary especially from Grouch. It is a display screen typeface with extremely tight tracking, and more than 2000 kerning sets for general even colour.
Letterspacing technique is TNT (that is Tight, Not Touching); an incredibly popular type treatment int the seventies and eighties.
