Calaveras County is one of the original 27 counties created when California was formed in 1850. At the time, it encompassed Alpine, Amador, and Mono Counties. Amador was the first to be separated in 1854, with Mono County following in 1861 and Alpine County in 1864. With the discovery of gold at Sutter's Mill on January 24, 1848, Calaveras County saw immigrants from every corner of the world. These pioneers brought with them the drive to make it rich and to make their lives and their families' lives better. Some did, and some lost their lives trying. Between 1848 and 1965, the county produced about nine million ounces of gold, valued today at over $18 billion. Today, tourism in Calaveras County supports approximately 2,400 jobs and contributes about $6 million to state and local taxes. Miners still find gold in the streams and rivers, families drive the back roads exploring the old towns and mines, and wine lovers enjoy wine tastings at the more than 50 tasting rooms scattered throughout the county.

Yuma County was created in 1864, following the organization of the Arizona Territory in 1862, and was one of the four original counties along with Yavapai, Mohave, and Pima. With the arrival of E.F. Sanguinetti and John Gandolfo in the late 19th century, a business empire was born and a community developed. Due to the creation of stores, farms, and the mining industry, the area's population grew from 4,415 in 1900 to 224,427 in 2015. Now a ghost town, the original county seat was formed in La Paz. By 1871, it was relocated 100 miles south to Arizona City, which was renamed Yuma in 1873. In 1982, Yuma County was divided in half, creating Yuma and La Paz Counties.

Originally inhabited by the Ohlone, Santa Clara County was one of 27 counties created when California achieved statehood in September 1850. The first settlements began when Fr. Junipero Serra established the Mission Santa Clara de Asis in 1777. For over 100 years, the valley was known for its rich soil and thriving farm region. In the 1940s and 1950s, William Hewlett and David Packard, along with Lockheed, IBM, and hundreds of other companies, altered the scope of Santa Clara County forever. With the influx of tech jobs and ensuing building boom, the county went from "Valley of the Heart's Delight" to "Silicon Valley."

In 1864, Arizona was divided into four counties named after the local Indian communities: Yavapai, Yuma, Mohave, and Pima. Believed to have been the largest county ever created in the lower 48 states at the time, Yavapai encompassed over 65,000 square miles until 1891, when the state was divided into additional counties. Yavapai finally settled to 8,125 square miles. While still a US territory in 1900, Yavapai County had a population just under 13,800 people and was quite remote. Within a few years, postcards started appearing in drugstores, such as Brisley, Timerhoff, Owl, Heit, Corbin and Bork, or Eagle Drug in Prescott and Lynn Boyd or Mitchell in Jerome. Many of the original postcards showcase early mines, towns, and buildings that no longer exist today.
