I came across this beautiful Pen and ink through Anthony’s post Leonardo DaVinci Drawings of the Royal Collection. This drawing is a study for the lost painting Leda and the Swan.

Although the painting is lost, copies exist. The drawing below is by Raphael who was interested in the figure in Leonardo da Vinci’s painting.
