Lope de Vega's Handwriting.

A handwritten sample of his script for La doncella Teodor (published in 1617) showing his elegant flowing style, matching his incredible fluency of composition, not unlike Shakespeare's. However, Lope is credited with some 3,000 sonnets, 3 novels, 4 novellas, 9 epic poems, and about 1,800 plays (many lost). Although the quality of all of them is not the same, at least 80 of his plays are considered masterpieces.
