This piece was auctioned late November 2014. Notice that the six clouds represent the original trading pits. The yellow Arcturus in the sky was a symbol used in the 1933 “A Century of Progress” Chicago World’s Fair. The two towers outside the building are actually on the inside of the building when you exit on Jackson Boulevard. The staircase railing was also brought outside of the building. Look closely and you will see tiny hand stitching of the building’s name. The building is appliquéd on the flag of Chicago.
