The UNPA was created in 1950, and the first stamps were issued in 1951. It has offices in New York, Geneva, and Vienna, and it’s the only postal authority in the world that issues stamps in three different currencies: US dollars, Swiss francs, and euros. These stamps are valid for postage only on mail sent from the respective UN offices. Their dual mandate is to generate revenue for the organization and to raise awareness about the UN’s work and global issues.

Women ranchers in the USA

Women ranchers in the USA have long played a vital but often overlooked role in shaping the country’s agricultural and cultural heritage. From the 19th-century frontier days, they worked alongside men to manage livestock, ride the open range, and endure the hardships of ranch life. Over time, women ranchers became landowners, business leaders, and key voices in preserving rural traditions.

On the postcard: An All-Around Hand. Wife, mother, roper, horse trainer, cook, bottlewasher, and much more.
