On Thursday I got two postcards from Belgium, a postcard from the Azores, a postcard from France and three maxicards from Thailand which were fixed together by tape.
One of the cards from Belgium shows the Pont des Trous in Tournai. The Pont des Trous was built in the late 12th century and is one of the last military river bridges in the World.
With a matching stamp:
EUROPA (from set of two) (issued 09-06-2018)
with First Day Special Postmark
Thank You very much Gerda!
