caption: The image shows a drawing of a table with a clock on top of it, which is believed to be a pendulum from the early 20th century. The pendulum is composed of a metal frame with a glass top and a metal base, and is connected to a metal rod with a series of wires. The metal frame is surrounded by a metal ring with a hole in the center, and the pendulum itself is suspended from the top of the frame. The background of the image is white, giving the drawing a clear and distinct look.
