Boston: Little, Brown and Co., 1937. First edition of his Pulitzer Prize-winning novel, a satire of Boston's upper class. INSCRIBED BY MARQUAND to noted book collector H. Tatnall Brown, "For Henry T. Brown Jr/ with kindest regards/ John P. Marquand" AND WITH TWO TYPED LETTERS SIGNED. In the first letter (4/3/39), Marquand agrees to sign books for Brown if he will send them with "cartons and stamps so that they can be dropped in the mail box." In the second (4/20/39), Marquand apologizes profusely for getting Brown's name wrong and offers various remedies--"I am mortified....perhaps this letter, pasted in the book, will be enough to show how seriously I was in error." Letters folded so contents visible and secured at corners to endpaper. 8vo gilt-stamped blue cloth over boards; top edge red; "Lovely Pearl" p.19 (vs "Pretty Pearl" in later printings). Tan vertical lines on pages, as normally seen, otherwise near fine in very good to near fine dust jacket with professional repair.
