DIANA, Princess of Wales (1961-1997). Autograph letter signed ("Diana"), to an unnamed recipient. N.p., n.d. 1 page, 12mo postcard showing a koala bear. In full: "I just wanted to write to say how very sorry we were to hear of your broken hand - it didn't by any chance happen the day Michael passed his driving test did it?! I do hope it's not too painful. It must make bathtime quite interesting, but we wanted you to know that we're thinking of you."
