Professor Stanley Wells, chairman of the Shakespeare Birthplace trust and one of the world's leading experts on Shakespeare studies according to the trust, poses next to a newly discovered portrait of William Shakespeare, in central London, Monday. The portrait, believed to be almost the only authentic image of the writer made from life, has belonged to one family for centuries but was not recognized as a portrait of Shakespeare until recently. There are very few likenesses of Shakespeare, who died in 1616. Lefteris Pitarakis
