There’s a famous film star in this photo. Mrs P noticed the person strolling by, not I. It made her day. Who is he or she? Typically, in Brit quiz style, you’d be asked to send in your answers on a postcard. But today, you can post your entries in the comments and I’ll send a London postcard to the first person who guesses correctly. You haven’t got the faintest idea? Have a wild stab in the dark anyway. For every wrong answer, I’ll provide a clue. You can keep making guesses, there’s no limit.
