BREAKFAST OF CHAMPIONS. [New York]: Delacorte Press / Seymour Lawrence, . Tall octavo, printed wrappers. Advance copy (uncorrected proof) of the first edition. Vonnegut's major bestseller, and his first novel after rising to literary prominence with SLAUGHTERHOUSE-FIVE. Fun, but perhaps his messiest novel, clunky, episodic, and sprinkled with felt-tip pen illustrations by the author. Also features the return of Kilgore Trout, Vonnegut's SF writer alter ego. Publisher's publicity photograph laid in. Vertical crease at center of front cover, title inked on spine panel, a nearly fine copy. (#102812).
