Stencil Package JNL has its design roots in the brand name hand-lettered on the paper sleeves for the short-lived Stencil-It line of lettering guides produced in 1955 as a direct competitor to Stenso Lettering Guides.

Formed by Bernie Aronson [a relative of the Libauers who owned the Stenso Lettering Company and who once worked for them] along with a financial partner (noted artist) Sidney Levyne, the company was soon put out of existence by a court action. It re-emerged in 1956 as the E-Z Letter Stencil Company and existed until the 1990s.

A detailed history of this type of lettering stencil was written by Jeff Levine and is hosted by fellow typographer Ray Larabie at his website.

Stencil Package JNL is available in both regular and oblique versions.
