The image shows the exterior of the Chicago Board of Trade building in Chicago, Illinois. The building is a tall, modern structure with multiple floors and glass windows. The facade of the building is made of beige-colored stone and has a large clock on the top. Above the clock, there is a sign that reads "CHICAGO BOARD OF TRADE" in black lettering. The sky is blue and there are other tall buildings visible in the background. The image appears to be taken from a low angle, looking up at the building.
