I almost fell in love with this picture, which shows a British Mk IV Female tank in the streets of New York. The building is of course the famous Flatiron Building located at 175 Fifth Avenue, completed in 1902.
This picture was taken during the Liberty Bond parade down 5th Ave, on 27th September 1918. Other pictures show the tank, named “Britannia” (as indicated by a banner with Britannia on it) with armoured cars of the NY National Guard in the background.
Some allied tanks were used as part of the Victory Loan fund raising.
