If you want Art Deco you need to go to South Beach in Florida. You will be greeted by some of the finest examples of the genre. You will also be greeted by some of the freaks that inhabit South Beach.
I saw Miami’s Deco in the late 80s and early 90s on a few trips.
Some cities still have remnants.
But it’s disappearing as real estate is replaced by out of state and out of country property investors.
