More lemons once were shipped from Corona than anywhere on Earth, as a dozen citrus packinghouses were located along the railroad tracks in this rural Riverside County enclave known for its circular boulevard and hard-working inhabitants. The postcards collected for this trip down Corona's memory lane reflect its six decades of citrus-industry dominance and portray the past in street scenes, commerce, ranches, schools, churches, homes, and the outlying resorts of Glen Ivy and the Norconian Club. The Corona Road Races-spectacular national affairs in 1913, 1914, and 1916-are also depicted.
