I received this poster as part of a private collection of airline posters. On receipt they were tightly rolled and unable to lay flat. In addition there were a number of tears around the edges from poor storage. In order to strengthen them I decided to line the back with a thin Japanese tissue using wheat starch paste. Additional cosmetic repairs were required on the front of the posters where tears and losses had occurred. On completion the poster was relaxed and able to lay flat in preparation for display.
