The image is an open book with two pages. The pages are divided into two sections. On the left side of the page, there is an illustration of a human leg with a diagram of the muscles and ligaments. The leg is shown in a side view, with the muscles labeled and the ligaments labeled. 

On the right side, there are two illustrations of the foot and ankle. The foot is shown with a black and white illustration of the ankle and the ankle joint. The ankle joint is shown as a small, circular structure with a small hole in the center. The bones are labeled with numbers and letters, indicating the location of the bones.

The pages also have text written on them, likely providing further information about the anatomy of the human leg. The background of the pages is white, and there are a few other illustrations scattered around the pages.
