This mural represents, he most important trading center of the region during the first years of XVI century, with streets specializing in products from the area and other regions of Mesoamerica such as pigments, jewels and even exotic seasonings.

The figure of tlatoani walking through the market may be seen in the forefront; while in the background there is, with great perspective, the Mexica city of Tlatelolco.
