Produced by companies and names such as Flexlume Oplex (the inventor of these formed glass plates), Opalume, Opalite, Wissmach Raised Glass, and others, opal, or “milk glass,” signs were a game changer from the 1900s into the middle 1930s because of their beauty and unmatched legibility, day or night.  Their popularity was, unfortunately, short lived as neon, with its relatively easy production and flexibility, took the electric sign industry by storm.

A century later, these letters are again available for restoration, reproduction, and new signage needs.
