To spread the word further about Post and Go / Self-Service Kiosks, Machine A007 will carry Union Flag and the Hong Kong design from Sea Travel. The additional inscription will be
UPDATE 1 December 2015
A special handstamp has been produced for this exhibition, not announced until today. It shows the Hong Kong skyline, with the wording
'31st International Asian Stamp Exhibition Hong Kong, Seaview'
Royal Mail's reference number is 13685 and this can be obtained from the London Special Handstamp Centre at Mount Pleasant.
Looking at the international stamp exhibition schedule in conjunction with the Sea Travel Faststamps, there is also New York 2016, so it seems quite likely that the New York Manhattan Skyline stamp from this set will also appear as a single-roll offering if Royal Mail take their Post and Go machines to the USA next May.
