A graceful finger of white, this "Spire to the Sun" dominates the graceful architectural scheme of the Golden Gate International Exposition on Treasure Island in San Francisco Bay. Four hundred feet high, - illuminated in amber, shading into a blazing white toward the pinnacle, this spire competes in stature with the towers of the two Greatest Bridges in the world, Golden Gate and San Francisco-Oakland Bay Bridge.
