Festival Hall and Cascades by night, Louisiana Purchase Exposition, St. Louis, U.S.A.
The Exposition buildlers succeeded in making the electrical illuminations the most spectacular feature of the World's Fair, with Festival Hall and the Cascades as the center of beauty ... More than 100,000 bulbs are used to produce the effect on Festival Hall and the Cascades. These light the waterfall and the fountains and bring out every line of the buildings with great clearness.
Three colors are used, white, red and green, and Art Hill with its buildings is made to glow in any one or all three of these colors. All the exhibit palaces are lighted every night.
