Just another busy day on Park Avenue

North of 42nd Street, Park Avenue is a pretty, orderly street practically glowing in vibrant shades of green, pink, yellow, and blue, according to this postcard from the 1930s. 

Notice the lack of crosswalk signs and traffic lights. The reason? Metro-North tunnels directly underneath made it difficult for these structures to be properly anchored into the ground.
