A lone farmworker stands knee-deep in an endless sea of cabbage heads stretching to the distant California foothills — a wicker harvest basket at their feet, suspenders crisp against a white work shirt, the scale of the monoculture crop almost surreal against the flat valley floor and mountain silhouette beyond. "A Cabbage Field in California" reads the caption in cheerful script, one of dozens of agricultural booster cards published by the Newman Post Card Co. of San Francisco and Los Angeles to trumpet the almost implausible productivity of California's irrigated valleys to an eastern audience still marveling at the state's potential. The card's No. AB98 places it in Newman's "On the Road of a Thousand Wonders" series — a promotional tagline for Southern Pacific Railroad tourism. The reverse is pristine and unmailed, its stamp box listing domestic, island possessions, Canadian, Cuban, Mexican, Panamanian, and foreign rates — a snapshot of America's expansive postal reach in the early 20th century.
