This was sent to me from a Postcrosser in Romania who organized a meetup event at the Voluntari Post Office outside of Bucharest, Romania. The event was held to commemorate UN World Post Day on October 9. He had a special postmark and postcard produced for the occasion. The pair of stamps on the left are Europa 2008 "Letter Writing" stamps. And the label on the right is an image of the postcard that was included in the cover.
