[John Singer Sargent, American expatriate artist] Autograph Note Signed John S Sargent to a Mrs Sturgis, declining an invitation

One page, 12mo, bifolium, second leaf laid down on part of an Album page, good condition. A scrawl. See Image. Text: I regret [so much?] not being able to accept your invitation - I have already booked myself elsewhere for that Sunday. | With best regards | Yoiurs sincerely | John S. Sargent. Note: Sargent's letter to a Mrs Sturgis has been extracted from an Album which mainly contains letters from distinguished writers (Hardy, George Eliot, Henry James, etc) to fellow author, George Meredith, or his daughter. Presumably she had a mainly family interest but was an autograph collector of sorts as well.
