Happy World Postcard Day 2020

World Postcard Day is celebrated each year on October 1.
In Austria-Hungary, Dr. Emanuel Herrmann (a professor of Economics from Vienna) wrote an article in the Neue Freie Presse pointing out that the time and effort involved in writing a letter were out of proportion to the size of the message sent. He suggested that a more practical and cheaper method should be implemented for shorter, more efficient communications.

His recommendations impressed the Austrian Post, who put them to practice on October 1st, 1869, resulting in the Correspondenz-Karte (Correspondence Card), a light-brown 8.5x12cm rectangle with space for the address on the front, and room for a short message on the back. The postcard featured an imprinted 2 Kreuzer stamp on the top right corner, costing half the price of a normal letter.
The postcard was born!
