Another innocent postcard needing a longer description.   Hongkong Post organised a series of tours of its Central Mail Facility in Kowloon Bay.  Only 30 people could join each tour, and they did this for a month.  At the end of each visit, they gave these postcards to participants.  The catch was:  it was a different postcard for each week, so if you wanted the other cards for the other weeks, in theory you needed to do the same tour three more times.  We chose not to do that, so this card represents Week 2.  We have one completely unused, and another with rubber-stamped “chops” on the reverse signifying our obligatory visit to the Postal Gallery.  Grades: 1
