PATA stands for Pacific Area Travel Association. Malaysia is one of the country members of PATA. In 1986, the annual meeting/conference of PATA was held in Kuala Lumpur (9-16 April 1986). Malaysia postal authority (later on known as Pos Malaysia) issued a set of six stamps on 14 April 1986 to commemorate the event. The event was also promoted through meter cancellation. For the event held in Kuala Lumpur, an official logo with motif of sea turtle was used.
