In New York, this would be prime time for a biplane pulling a long ad banner. In Germany, it's something like this, which we noticed was indeed an adfor Rimowa luggage. The underside of the wings sport both the Rimowa logo and trademark phrase: Die Koffer mit den Rillen (the luggage with the ribs).
With some Googling, we've discovered that the airplane is a 1949 Junkers JU-52, a German-made trimotor and is, as expected, an aircraft of huge importance in the history of aviation. Enjoy our shots while we try to process the fact that we caught it and managed to get our camera out in time.
