Philippe's work is wonderful.Is this an old stamp in francs? How does La Poste handle use of older stamps?
Yes this is an old stamp in Francs. In France all stamps produced by the French post since the beginning (except some exceptions like the stamps puctiring Petain) are valid for postage. You have to make sure the conversion euro/francs gives the right franking. I guess the postal clerks do the check manually. I don t think these type of letters goes through the machines.
