The last Guess The Year post was a little too easy (read: find-able on the internet), so all we're going to tell you about this one is that it was taken on July 4th... do you know the year? We'll update later with the answer, and more details about the photograph.

UPDATE: The photo was taken in 1953, and shows a NYC Police helicopter hovering over the East River near a daytime tour boat. That's the Queensborough Bridge in the background.
