Francisco José de Goya y Lucientes (1746-1828) usually just signed "Goya" with simple and unadorned letters. He also had a longer more decorative signature "Fran. de Goya" in which the tail of the final "a" curls around several times.
Some scholars now believe that miniature signatures can be found throughout his paintings. Many tests have been done to reveal the micro "Goya" signatures.
Goya also signed some of his etching plates but his editions are not usually hand signed.
