Autograph letter from the influential novelist and playwright whose works include the classics Babbitt, Elmer Gantry, and Main Street. In 1930 he became the first American to win the Nobel Prize in Literature. ALS, two pages, 5.75 x 7.25, Hotel Atlantic, Berlin letterhead, July 27 [envelope postmarked 1929]. Lewis writes to Freeman Hopwood. In full: “Several good letters from you. I’m working here—may stay all winter. S. Parks Cadman has been in London, attacking the Godless, including me. The Lit Digest reprint of Cray is superb. I’m so glad you’re keeping after the colleges.” After signing, he adds a postscript: “I probably shan’t do a second preacher novel [evidently referring to Elmer Gantry] just now—let it simmer, lest I merely repeat myself.” Accompanied by the original mailing envelope. In fine condition, with scattered toning and spotting.
