A search of original copyright registrations for the year 1956 shows only one phot of the vessel registered. It was taken as the Andrea Doria was outbound from Italy on this last voyage.
Checking copyright.gov turned up no renewals for en:Boston Evening Traveller, which went out of business in 1967, or Harry Trask, the Boston Traveller photographer who took this photo.
A check of original copyrights in artwork for the year 1957 found no Andrea Doria registered photos, so Trask or the Boston Traveller didn't decide to register this photo in that year.
Checking renewals at copyright.gov found none for the St. Paul Pioneer Press, who published this photo in 1957. There's no evidence of present copyright on the photo.
