Old postcards

I've been mailing these old cards to old lake friends. (And using my old 25¢ New Hampshire stamps to mail them).

The post office requires 1st class postage (37¢) on cards sized smaller than 3½ X 5 inch. (Many old cards are slightly smaller than 3½ X 5 inch).

Some of those old postcards are pre-stamped with uncancelled 1¢ stamps!
