Advertiser JNL is a simple A-Z only font used to make retro-styled titles and names. Based on a popular style of retail signage from the 1950s and 1960s, alternating keystrokes will create a contrast of positive and negative letters. The capital letters have the alphabet in white on black boxes, the lower case have the black letters alone—with the white space conforming to the width of the black boxes.

In a pinch, the boxed characters can also be used as initial caps. For a more complete character set with the same style of lettering, use DuBois Block JNL.
