Vintage circa 1910s-1940s blue porcelain 'humpback' New York City street sign in a metal holder, measuring 28.5 x 13, for "5th Ave. / W. 51 St." In fine condition. One of the most famous streets in the world, Fifth Avenue is home to a luxurious retail environment as well as historic landmarks including the Empire State Building, Flatiron Building, and Rockefeller Center. Located at the corner of 5th Ave and West 51st Street—the location of this sign—is St. Patrick's Cathedral, probably the most famous church in New York. A superb relic from one of the world's great cities.
