In celebration of my father's birthday, I uploaded some vintage birthday postcards postmarked from 1901-1904. Mail cards were popular during the Golden Age and cost one cent to post. The United States Postal Service issued the first postcard on May 13, 1897. This Golden Age boom of the postcard lasted until about 1920 when the telephone took off. I love reading the backs of postcards. One I read, the lady told her brother he could bring his cow to her house next time he visited. Love reading the real lifestyle of the era!
