Said to be a portrait of William Shakespeare, age 24, 1588. Interestingly, one famous portrait of him, used for centuries in literature of all sort, is actually a fake (made from a theatre mask). No conclusive portraits has ever been found of him (or them). Privately, some historians still believe he wasn't a single figure, but group of unidentified writers who worked under the Shakespeare identity. There has been many such mysterious writers in history, this one is most famous up-to our time.
