The image is a photograph of a rectangular plaque on a grassy lawn. The plaque is made of red granite and has a white background. On the left side of the plaque, there is a list of names and dates written in Spanish. The list is titled "Limite del Recinto Sagrado, Altar Hemisfierico DT y Calzada al Tepeyac" which translates to "Limited to Recinto Saguaro, Altars Hemisférico DT and Calzadas at Tepeyaac". Below the list, there are three illustrations of birds. The illustrations are in black and white and are arranged in a grid-like pattern. At the bottom right corner of the image, the word "INAH" is written in a cursive font.
