Leonardo da Vinci's Old Man and Water Sketch Key Ring

Studies of an old man and the action of water (c. 1513) by artist Leonardo da Vinci (1452-1519) is a vintage Renaissance Era fine art self portrait painting. A drawing featuring Leonardo as an old man with a beard and several views of how water flows. 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.
