The description for Lot 373 (pp.423-426) includes the text of a brief note (dated 17 August 1954) from Tolkien to his son Michael, composed to accompany a First Edition presentation copy of The Fellowship of the Ring.
In the note Tolkien thanks Michael for his assistance with the typing of the book, and comments on its critical reception. The note is reproduced in a photograph. Tolkien added a comment on the verso of the note, suggesting that Michael’s son was probably old enough to enjoy the book.
The note is not included in The Letters of J.R.R. Tolkien (1981).
