caption: The image shows a drawing of three different types of coffee urns on a piece of paper. The urnes are arranged in a triangular formation, with the largest one in the center and two smaller ones on either side. The largest one is a cylindrical shape with a handle on the top and a spout on the side, while the smaller one is slightly larger than the one on the bottom. All three vessels have a metallic sheen and appear to be made of metal.
