1980 (05) Landmarks - PO - Kingston Upon Thames H/S - Doubled on the First Open Day of Buckingham Palace

Unusual Post Office cover..........

Kingston Upon Thames H/S, but then doubled on the First Open Day of Buckingham Palace being 'open' for visitors....

Only 250 serviced this way - the cachet's do remind me of the 'Bradbury' way of doing these things, but nothing on the cover to confirm it one way or another....
