The image shows a large jet engine on display in a museum. The engine is mounted on a metal stand and is in the center of the image. It is a large, circular engine with multiple pistons and valves. The pistons are arranged in a circular pattern around the center, and the valves are located on either side of the engine. There is a label on the engine that reads "Boeing" and appears to be a description of its purpose. In the background, there are other aircrafts and exhibits on display.
