The image shows a close-up of a fireman's helmet displayed in a museum. The helmet is made of metal and has a pointed top with a curved brim. The front of the helmet has the words "Marshall Chicago Fire Department" and "WHM" embossed on it in black lettering. The sides of the hat are decorated with a pattern of small circles and lines, and there is a small emblem on the side that reads "Fire Department." The helmet appears to be old and worn, with some scratches and scuff marks on the metal. In the background, there are several framed photographs and artifacts on display.
