postmark

The letter had lain at his Club three days, it was dated Switzerland and the postmark was Montreux.

By the way, any letters bearing a certain postmark, that come addressed to me during my absence, Taylor has orders to send to you.

Ohio postmark for postmarks from any other State, and old issues of United States postage and revenue stamps for foreign stamps.

A comparison must have been interesting to you, by the same mail presumably, under the same postmark.

The letter came from beyond sea; it was addressed to Mess Lethierry, and bore the postmark "Lisbon."
