P&O: Some lucky soul took a 1971 cruise on a P&O ship that docked at St.Thomas, Barbados, Martinique, Grenada, and Teneriffe. P&O distributed these fold-out port guides at each stop. They include a map, port history, and tourist info such as beach and toilet locations, public transportation, and the local P&O office address. These are a reminder that the mighty P&O once docked in 100 ports 'round the world. That was true when these guides were printed in 1971, but by mid-decade most of the service had been abandoned and the ships shuffled off to the breakers.
