The front page of a late-1940s sales catalog for the [now defunct] Duro Decal Company of Chicago had its company name hand-lettered in a tall, condensed chamfered sans serif type design.

Although chamfered lettering had been popular for decades, the way the “R” was shaped gave the letters a bit of an Art Deco influence, and this influence was carried through in the creation of Durable JNL.
