The famous British ocean liner Queen Mary arriving from Europe to New York, June 20, 1945 with thousands of returning U.S. Army personnel.  During the war years she was converted to a troop transport vessel and was painted "navy grey".

I tried to correct your photo so it is easier to view. Hope you do not mind.

Found this photo recently, not sure of the date. My Father, Alex D'Ambrosio is in the back row leaning over. Cannot identify any other soldiers in the pic. Would like to know if the individual front and center is AAF or Tanker?
