Since this is the first stamp fair after the PSM covers were made in Thailand 2016, expect the covers to be on sale. In addition, Pos Malaysia might spring some surprises similar to what they have done in previous stamps fairs post participation in a major stamp exhibition.

Will there be special cancellation on 2nd day?
Not that I am aware of. So far PSM Stamp Fairs do not have special postmarks. However in December 2016, the stamp fair will be held together with a national stamp exhibition. There will be stamps issued during that week. Stay tuned for more information.
