The image is a photograph of a sign on a wall that reads "Bronze Ge with Variant Forms in Chronological Order". The sign is rectangular in shape and has Chinese characters written on it. The text is written in both English and Chinese characters. Below the text, there is a table with three columns and three rows. The first column lists the different types of bronze ge with variant forms, the second column shows the type of ge, and the third column displays the type.

On the right side of the sign, there are two smaller signs with Chinese characters, one in English and the other in Chinese. The sign on the left side has a list of the types of ge with different forms, such as the Bronze Ge with Variant Form, which is used to measure the size and shape of the ge. The signs are arranged in a grid-like pattern, with each type represented by a different color. The background of the image is white.
