This is a linen-era postcard featuring a scene from a San Diego exposition. On the card itself, it is identified only as "San Diego Exposition," but it was probably the "California Pacific International Exposition," which was held in 1935-36. Linen-era postcards were printed from 1930-1945.
The card was never used.
On the reverse side, the following is found:
"Cabrillo Bridge: 135 feet in height and a quarter of a mile in length forms a graceful approach to the western entrance to America's Exposition at San Diego."
It was published by Western Publishing & Novelty Co., Los Angeles, California
