Mr. Lloyd Lewis from California had approached me with a proposal to do a large-scale project involving several illustrations. The objective was to produce anatomical charts representing in detail the muscles of the human body in the three main points of view (anterior, posterior, lateral). Each part of the body had to be presented independently and each muscle had to be isolated and clearly identifiable.

In addition to the superficial muscles, it was also necessary to represent the more internal layers up to the bone structure. First of all, it was required that I build the complete skeletal structure, and then to illustrate how and where each muscle is attached to the bones.
