Lewis Carroll, A Biography and Selected Letters
Two paperback volumes by Professor Morton N Cohen
1995 & 1996, two first printing paperbacks.
Two books by Professor Morton N Cohen, the pre-eminent Lewis Carroll scholar. His well-regarded biography of Lewis Carroll, and an edited version of his 1979 Letters of Lewis Carroll.
Both books are in very good condition and appear unread, though the Letters has some tanning to the pages.
