Leonardo da Vinci's Wing on Flying Machine Sketch Cushion

Wing of a Flying Machine (c. 1480) by artist Leonardo da Vinci (1452-1519) is a vintage Renaissance Era fine art engineering painting. A drawing featuring the detail of a wing section of an aircraft. Great design for a pilot 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.
