Designed by Jeff Levine, Photo Developer JNL is an art deco font family. This typeface has two styles and was published by Jeff Levine Fonts.
An image found online of a vintage storefront sign for the Kraus Photo Shop was the inspiration for Photo Developer JNL, which is available in both regular and oblique versions.
The sign featured a thick and thin Art Deco style lettering with an inline cutting through the thicker strokes.
Before the advent of digital photography, and way before chain stores offered in-house processing, neighborhood photo labs were the only place for getting prints from your roll film (unless you wanted to send the film into Kodak for developing and printing).
Customers of these stores could also purchase additional film, cameras and photographic accessories from the same location.
