UX1,
1c Jefferson Postal Card Used in
Hong Kong Endorsed
on reverse Mailed "on board" in Hong Kong
I must say
that this card was obtained at a basement price
of US$ 19.75
(ebay) by "aerophilatelist". Although without a Hong Kong postmark,
this one is
still a real beauty.
The other possibility
is for the card to be used in Guam, Puerto Rico,
China and
Cuba (commercial or philatelic).
