The image shows a model of a steam engine on display in a glass case. The model is made of metal and is displayed on a wooden base. The engine is gold in color and has a cylindrical shape with a chimney on top. It has a red wheel on the left side and a small engine on the right side. There are two pipes on either side of the engine, one on top of the other, and a smaller pipe on the bottom. The steam engine appears to be old and weathered, with some rust and corrosion visible on the metal. There is a label on the top right corner of the display case that reads "Model of a Steam Engine".
