Category: Undivided Back Era (1901-1907)

The Undivided Back Era, which lasted from 1901 to 1907, is characterized by a unique format in which the back of the postcard was reserved exclusively for the recipient’s address, while any personal message had to be written on the front, typically around the image or in a designated space if provided.

The era ended around 1907 when postal regulations changed to allow divided backs. This new format provided a designated space for the address and a separate area for the message, revolutionizing postcard design and use.
