#990 France 15/10/12
Mr. A. has sent this very nice cover from France, thank you! It was posted in Dunkirk (Dunkerque) on October 12 and arrived on October 15, 2015.
The top stamps are part of the sets “Famous Frenchmen”, which were issued on February 14 and April 11, 1970. They commemorate Maurice de Broglie (1875–1960), Louis Le Vau (1612–1670), Philibert de l’Orme (c. 1514–1570), and Édouard Branly (1844–1940).
The bottom left stamp was issued on March 26, 1949. It commemorates the Stamp Day.
