The image is a photograph of a sign on a wall that reads "The Urban Explosion: Cities increase in size and number". The sign is rectangular in shape and has a white background with black text. The title of the sign is written in bold letters at the top, followed by the subtitle "3,500-2,900 B.C." Below the title, there is an illustration of a map of Uruk and Jamat Nasr Periods. The map is in the center of the image and shows the cities that have increased in size over time. 

The map is divided into two sections, with the top section showing the cities and the bottom section providing information about the urban explosion. The cities are located in the Uruk region of the United Arab Emirates and are known for their rich history and culture. The text below the illustration explains that the cities increase in the size of the city and that it is one of the most important early cities in the world.
