Leonardo da Vinci's Anatomy of the Human Hand Keychain

Several views of the anatomy of a human hand (c. 1510) by Leonardo da Vinci (1452-1519). A vintage Renaissance Era fine art science painting featuring several views of the internal workings of a human hand. A drawing including the bones, skeleton, muscles and tendons. Great design for someone in the medical field or a science geek. Sketch 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.
