I had been unaware of it, but NYC’s Department of Transportation officially refers to these type of street signs as “camelback” signs, instead of my own appellation, “humpback” signs. I suppose it’s classier that way.
This sign adorns a gate at Washington and West 10th; when in use in the early to mid-20th Century, it was fastened on a pole several dozen blocks further downtown.
