Unisex bathroom in style

Despite the current high profile of transgender facilities, unisex bathrooms have always been a thing. Didn't  you grow up with one? I certainly did.
And in the late 60s, they were not uncommon in bars, particularly in liberal college towns.
As a graphic designer, I love this simple elegant design that clearly states the nature of this restroom. Two figures, six metal pieces - only slight positioning differentiates the two genders.
This cool door and some great craft beer can be found in the Vortex Alley Brewery, Ponca City, Oklahoma.
