I found this maybe close to the date of the pic?
It took a while before the work was finished, but on May 5th 1950, the Empress of Scotland set out on her first post-war voyage, from Liverpool to Quebec. Outwardly, she was very much alike her pre-war self. The white hull was there, but the three funnels now sported the new CPR livery, adopted in 1946 yellow, with the company flag superimposed.
The Empress of Scotland soon settled into her new service. She ran on the Liverpool-Greenock-Quebec service during the summers, and in the winters she was sent off cruising the West Indies out of New York. In April of 1952, the ships masts were shortened in order to allow her to pass under the Quebec Bridge and continue to Montreal, which had now been dredged to her draught. On May 13th she made her first sailing from Liverpool to Montreal.
The ship continued to serve Canadian Pacific through the 1950s, but circumstances would soon see her leave the company. In 1956, the brand new Empress of Britain entered service, followed by her sister Empress of England the next year. Suddenly, the Empress of Scotland was an old ship compared to her fleet-mates, and she was subsequently laid up at Liverpool on November 25th, 1957. She was later dry-docked at Belfast and put up for Sale
by the company.
