I have been sleeping for a while on this blog. Saw these stamp kissens somewhere.
In the middle a kissen with a stamp with a "Gros Chiffre" obliteration 455.
This is the 455 for "Bercy", currently the 47th "quartier administratif" in Paris (12th arrondissement).
"Bercy" is now synonymous with the French Ministry of Economy, Finance and Industry that is found there.
Who recognizes the other stamps?
