Lasting Impression JNL was rendered from scans of a 1930s rubber stamp printing set. At small sizes it has the look of hand-stamped lettering. At larger sizes, the user will see jagged and angular lines giving the font a kind of retro-grunge look. This typeface was the model for the more cleanly-drawn Casual Friday JNL, also by Jeff Levine.

There is a limited character set, and both the spacing and kerning have been intentionally omitted so that the results will more closely resemble the uneven letter spacing of rubber stamps on paper.
