Letter link: Carpenter #144: Letter from J.R.R. Tolkien to Naomi Mitchison • 25 April 1954 (#372)

I note two different dates of this letter are given in LR Reader's Companion (p101, p683: 14 April 1954) and History of The Hobbit (p283 in 2 vol ed: 24 April 1954). But both authors are quoting from Letters, and used "25 April 1954" elsewhere in their books. Descriptive Bibliography p359 also suggests the Sotheby catalogue used 25 April, so I guess that should be the correct date.
