Uvex wasn't the only company responsible for producing molded plastic signage, but it did have some reasonably nice marketing materials. Concepts in Uvex, their trade catalog promoting their modern and "versatile, high impact plastic sheet" of "lustrous beauty" was published in the 1960s. No designer listed, but it certainly has the earmarks and influence of Alexander Girard's colorful work. And you gotta love the Vanna White of plastic molded letters.
