Arm and Shoulder Anatomy by Leonardo da Vinci T-Shirt

Arm and shoulder muscles (c. 1510) by artist Leonardo da Vinci (1452-1519). This drawing or sketch is a vintage Renaissance Era fine art science painting. Human upper body muscle structure including arms and shoulders. Great design for someone in the medical field or just a science geek. Sketches from one of Leonardo da Vinci's many journals. Leonardo kept a series of journals in which he wrote almost daily, as well as separate notes and sheets of observations, comments and plans which were left to various pupils and were later bound. Many of the journals have survived to illustrate Leonardo's studies, discoveries and inventions. Most of the journals were written backwards in mirror script. His journals were later published, 165 years after his death.
