The image is a yellow sign attached to a chain link fence. The sign is written in Japanese and appears to be warning people not to enter the area. It has a cartoon illustration of a man wearing a green shirt and a hat, holding a stack of books in one hand and a red "No" sign in the other. On the right side of the sign, there are illustrations of a group of people, including a man and a woman, standing on top of a pile of books. Below the illustration, there is text in both English and Japanese. The text on the sign is in red and yellow colors.
