The theme of the 1939 World's Fair known as the Golden Gate International Exposition was "The Pageant of the Pacific". It was a celebration of the products of Pacific Rim nations, as well as San Francisco Bay's recently opened Bay Bridge and Golden Gate Bridge. Treasure Island, the flat, man-made area attached to Yerba Buena Island, was constructed specifically for the Exposition.
Many San Leandro school kids went on field trips to take in the educational exhibits.
San Leandro seized the opportunity to show off its own products, as demonstrated by these two photographs.
To see many lovely postcards of the Exposition, visit the San Francisco Bay Area Postcard Club's Exposition collection here:
Thanks to the San Leandro Public Library's San Leandro Historical Photograph and Document Collection for these two photographs.
