Superb lithograph of the California motherlode, thought to be by the California-based artist and lithographer George H. Baker, descended in his family until its recent purchase by the current owner. George H. Baker (1827-1906) made his way to San Francisco through Mexico in 1849, arriving on May 28, 1849. The product of private schools in Boston with artistic training at the Academy of Design in New York City, he turned his talents to recording the Gold Rush in both prose and picture. His lithograph "Port Of San Francisco 1849" appeared in the "New York Times" that same year. In 1856 he became editor and publisher of the Granite Journal at Sacramento. He also engaged in the lithographing business in that city until 1862, when he established his home and business headquarters in San Francisco. From 1862 until his retirement, about 1890, Baker conducted a leading lithographic establishment and business in San Francisco. In 1873 in Yosemite, he sketched scenes that became part of a Pacific Coast set of lithographs.
