The image is a photograph of a sign on a red wall. The sign is written in Korean and appears to be explaining the history of the ancient city of Seoul, South Korea. The text on the sign is in black and white and is divided into two sections. 

On the left side of the sign, there is a list of information about the city, including the names of the buildings, streets, and other landmarks. On the right side, there are several icons representing different types of buildings and structures. The icons are arranged in a grid-like pattern, with each icon representing a different type of building or structure.

At the bottom right corner of the image, there has a QR code, which is likely used to access the information on the board.
