The image is a collage of three photographs of a machine. The photographs are arranged in a grid-like pattern, with each photograph showing a different part of the machine.

The first photograph on the top left shows a close-up of a steam engine with various gauges and controls. The gauges are labeled with numbers and letters, and the controls are labeled as "Air pump, 60 PSI", "Ejector, open all the way", "Left injector supply", "Blower", "Dynamo", and "Cylinder Cocks". The second photograph in the middle shows the engine with its various components labeled, including the valve, valve cover, and valve stem. The third photograph shows the right injector and cylinder cocks, which are used to control the flow of air through the engine. The image appears to be taken in a workshop or garage, as there are other machines and equipment visible in the background.
