autograph letter signed to Mrs Gielgud (mother of John Gielgud?),

2 pp, 12mo. She thanks her for her "sweet present", and then makes what appears to be a reference to John Gielgud: "I'm taking Betty tonight to see John - her first evening performance! She is so thrilled. I am so sorry he has been so reedy, but perhaps the enforced rest will do him good." Slight traces of adhesive tape to left-hand margin of recto.
