A great old map promoting the use of the H&M tubes (now known as PATH) for rapid access to Manhattan and beyond (Ebbets Field, Coney Island!). 

Although undated at the original source of the map, it’s pretty easy to narrow it down to sometime between 1950 and 1953 due to the presence of the 3rd Avenue Elevated in Manhattan. As shown, it no longer goes to South Ferry (closed 1950), but still continues to City Hall (closed 1953). I feel sure it could be dated even more accurately by those more familiar with New York’s transit history than me.
