Strongbox JNL is based in part on an incomplete sample of an old wood type alphabet seen on an image sharing site. Commonly known as a grotesk (or grotesque) face, this style of sans serif lettering is well-suited for headlines, display work, price cards or anything where a bold, condensed typeface is needed.

An old Art Nouveau typeface named "Daphne" provided the inspiration for this decidely different font. This version is upright, but the linocut treatment employed visually suggests the slight rightward slant of the original typeface. Bold, unusual and distinctive. Both versions of the font include 1252 Latin, 1250 CE (with localization for Romanian and Moldovan).
