As long as I've been alive (since 1960) Joe Daiches Credit Jewelers has had a storefront in downtown Fort Worth, one block north of the Tarrant County Courthouse.
Also, for about the same amount of years the sons of the owner, Alvin and Larry, made these god-awful, clumsy 30-second commercials on local t.v. that were hilarious because they tried to be funny but the fun part of the spots were them, they're stiffness, comfortableness, etc. They were a couple of dorks who meant well but should've hired one of those loud car salesmen instead. At the 1:36 mark of this video you can watch one of their commercials. It's from the '70s.
Now, there's no telling how old its neon sign is but I found on a genealogy site the man who owned the company who produced it. You can see at the very bottom of the sign (click on the sign to see the full version of it) the words "Melton Neon." Well, from that genealogy site this is what it says about Mr. Melton, "Julian Chappell Melton was born on 6 Sep 1898 in Lima, Beaverhead Co., Montana. He died on 31 Aug 1984 in Fort Worth, Texas. He was buried in Mount Olivet Cemetery. Lived 86 years. Julian had golden hair and bright blue eyes and was very handsome. He was an fighter pilot ace in the first World War. After a plane crash he went to the hospital at Berrings Field, Texas. He recovered completely. He owned the Melton Neon Sign Company on East Lancaster in Fort Worth, Texas. He was also an artist."
Of course, the man's company no longer exists but, obviously, his firm did good work.
