How does Kurt Vonnegut use imagery in God Bless You, Mr. Rosewater, or, Pearls Before Swine?

Imagery:

"So, when King Eliot and Queen Sylvia took up residence in the Rosewater Mansion, they were showered by figs from Avondale - invitations, visits, flattering notes and calls. All were deflected. Eliot required Sylvia to receive all prosperous visitors with an air of shallow, absent-minded cordiality. Every Avondale woman left the mansion stiffly, as though, as Eliot observed gleefully, she had a pickle up her ass." Chap. 4, p. 49

"Eliot made of his mouth a Cupid's bow, murmured something sweetly, turned over, snored. He was an athlete gone to lard, a big man, six-feet-three, two hundred thirty pounds, pale, balding on all sides of a wispy scalplock. He was swaddled in the elephant wrinkles of war-surplus long underwear. Written on gold letters no each of his windows, and on his street-level door, too, were these words: Rosewater Foundation How Can We Help You?" Chap. 4, p. 62
