Chelp is a grunge display font, in 4 different styles: there’s a Regular and All-Caps version, plus a Dirty version which has little bits of overprint like the edge of the stamp has accidentally marked the paper, and a Jumbled version where the characters are misaligned in various small ways, or are at slightly odd angles.

Chelp contains quite a few Open Type features, such as auto-replacements for all double letter combinations from AA to ZZ, and aa to zz --- which will automatically produce two different letters rather than the same one twice, to give the variation in display that gives grunge printing a greater degree of authenticity; and there’s stylistic alternatives for all letters A to Z and a to z in all the two-case versions; plus the usual conventional OT features, and accented characters for Western and Central European languages.
