ALS, one page, 7 x 9, personal letterhead, July 31, 1929. Wells writes to the author of an unspecified work. In part: “Your book is very interesting both as an experiment & in its math and treatment. I think we want a great range of such books telling the same story to different sorts of people. The important thing … is not that it should be one book but one story & one attitude.” In fine condition, with mailing folds, a few small scattered spots, slightly irregular top edge, and small adhesive remnant at lower left, none of the flaws materially affecting the visual appeal.
