Book excerpt: Riverside has been a vital center of agriculture and government throughout the growth of Southern California. Postcards sent from this city to those far away usually depict it as a resort, situated on the western edge of the Colorado Desert, where the historic Mission Inn has been a vacation destination for generations. Illustrating many facets of this world-renowned, garden-like gathering spot, these attractive images also showcase Riverside's Main Street, public buildings, parks, broad avenues, the sharply rising Mt. Rubidoux on the edge of town, and the influence of the citrus industry.
