The 1930s era French textbook on lettering "100 Alphabets Publicitaires déssinés par M. Moullet" featured a hand lettered chamfered alphabet with slab serifs reminiscent of sports lettering. Although intended for advertising and signage inspiration, only a partial lower case was illustrated along with the capitals and no numbers or other characters existed. These had to be created from scratch.
The finished result is not only a bit of classic lettering from the past, but the font also doubles as a typeface with a sports look and feel.
A traditional (rather than stylized) M and N are located on the solid bar key and the broken bar key respectively.
Old Sport JNL is available in both regular and oblique versions.
