Dunno if it's possible to say which liner this is-- go to www.corbis.com and search for UB1081DINP. It's a view of New York harbor (taken from the Singer Building no doubt) sometime around WWI. (The pic is backwards.) The Britannic never crossed the Atlantic, did it? So are there only five possibilities, the three Cunards and the Olympic and France? The only other four-stack liner that visited NY was the Deutschland and with the evenly-spaced stacks it can't be them?
