Private Mailing Card through photochrome, with the limits of era-based dating.
Pioneer and Private Mailing Card periods
The Library of Congress places the postcard pioneer period broadly between 1870 and 1898. A federal act in 1898 allowed private printers to sell cards at the one-cent rate using required Private Mailing Card wording.
Undivided backs
Smithsonian chronology identifies a 1901–1907 undivided-back period in which privately printed cards could say “Post Card,” but the address side still was not divided for a message.
Divided-back Golden Age
In 1907, U.S. rules allowed privately produced postcards to divide the back between message and address. Smithsonian sources commonly describe 1907–1915 as the divided-back Golden Age.
White-border trend
The Smithsonian associates the white-border period broadly with 1915–1930, when U.S. production grew and white borders conserved ink.
Linen and photochrome
Linen-style cards are most strongly associated with 1930–1945. Modern photochrome-style cards appeared in 1939 and became dominant after World War II.
