U.S. Customs House
Most of the granite sculptures on the U.S. Custom house were done in-situ by unknown artists.
The roof top sculpture, however, was done by Alice Cooper. Alice Cooper (April 8, 1875 – 1937) was an American sculptor.
Born in Glenwood, Iowa, and based in Denver, Colorado, Cooper studied under Preston Powers (son of the well known sculptor Hiram Powers,) then at the Art Institute of Chicago with Lorado Taft and the Art Students League of New York through about 1901.
Cooper is best known for her bronze figure of Sacajawea originally produced as the centerpiece for the Lewis and Clark Centennial Exposition in Portland, Oregon, 1905, unveiled in a ceremony attended by Susan B. Anthony and other prominent feminists. This figure now stands in Washington Park.
Regarding the sculpture. The figure on the right holds a staff with two snakes coiled around her left arm. The figure on the left holds a two handled vase in her right arm.
Nice catch wit the flag behind it!
