When I read that, I thought of the Frolic Room neon next to the Pantages, which itself has neon signs. I don't know if those signs are the originals, but they still look like the neon in photos of yesteryear.
Then there's the story, when Clifton's Cafeteria was being remodeled, of finding the neon light that had been burning for 77 years. From
Allison Martino/Vintage Los Angeles:
While updating the 47,000-square-foot space, Meieran’s team made an amazing discovery! While restoring a woman’s restroom, they noticed a neon bulb burning brightly behind a wall. Behind layers of plywood was a light panel that had been covered by plaster for 77 years. Someone forgot to turn it off during the Great Depression and today the light is the oldest existing neon bulb still working in the entire world. Meieran has said the lit bulb cost $17,000 in electrical bills over the years. It will be on display when Clifton’s officially reopens (so long as it doesn’t burn out before that).
I read an article recently about the American Legion Post 43 in Hollywood (it's having issues) and the beginning of the article said, "A historic original neon sign glows outside the Hollywood Post 43 American Legion..." So I tried looking up when it was installed. The building is said to have been built in 1929.
In a Google search one of the results was this:
Hollywood Chamber of Commerce
Hollywood Post 43 - American Legion · Media. Original Neon Sign 1936
But I went to that site and found the image, but there was no info I could find about the date it was installed.
Hollywood CHamber of Commerce
I looked at older b&w photos and didn't see the sign in them, where the sign is now anyway, it could have been moved. I did see this 1938 photo which shows a sign, bottom left, that could be the neon sign, but if it is, it had another section added underneath it (see above) that says Hollywood | Post 43.
