Grubb's Marine in Spring City, PA, was a dealer for Duratech in the 1950's to very early 1960's. This sign would have been purchased new by them in the late 50's. It has been a part of my personal stuff ever since. It measures about 25" wide X 10" high X 3 1/4" thick. The first picture shows it plugged in and lit. I have never seen another of these. I am downsizing and decided it is time for the next owner. Thanks for looking and bidding. Bob Grubb
