This stamp, issued on the 100th anniversary of California's admission to the Union, is a rich tapestry of the state's economic and historical development. The central figure of a gold miner pays homage to the Gold Rush, the catalyst for California's rapid growth. Surrounding the miner are symbols of the state's diverse economy: citrus fruits and grapes representing its agricultural prowess, and oil derricks signifying its industrial strength. The inclusion of a steam train and a ship highlights California's role as a vital link in national and international trade. The stamp's design encapsulates the journey of California from the wild frontier of the Gold Rush to a modern economic powerhouse, celebrating a century of progress and prosperity.
