The image shows a display case with a sign that reads "Spear of Xi, King of the State of Yan, of the Period of Warring States (provi-ded by Hebei Research Institute for Cultural Heritage)". The sign is rectangular in shape and has Chinese characters written on it. In front of the sign, there is a small knife with a black handle and a pointed tip. The knife appears to be old and weathered, with some rust and discoloration visible on the blade. The background is a plain white surface.
