PPC Posted On The High Seas with cachet in violet R.S.S Atlantis. 1935.

Double ring May 3rd Palma de Mallorca. Panaramic Scene depicting Portofino. Received at Worcester.

RSS Atlantis was previously the Andes. In WW1 she was part of the 10th cruiser squadron in the North Atlantic. In 1929 she was refitted  as a luxury liner and renamed. Her typical routes took in the Med and I guess this was sent whilst on such a  cruise in 1935.

In 1939 she was refitted into a hosp ship at Southampton.
