This classic chart of The Muscular System was illustrated by Peter Bachin in 1947 and continues to be one of the most easily recognized images in medical illustration. Every illustration is vividly colored and finely detailed. All structures are clearly labeled. The large central illustrations show both anterior and posterior views of the male muscular system. • Four smaller illustrations show : • the muscles of the right hand • the right half of the diaphragm • muscles of the posterior abdominal wall • muscles of the right foot.
