Harvey Kurtzman's Jungle Book, Or, Up from the Apes! (and Right Back Down).

"Harvey Kurtzman's Jungle Book is a graphic novel by American cartoonist Harvey Kurtzman, published in 1959. Kurtzman aimed it at an adult audience, in contrast to his earlier work for adolescents in periodicals such as Mad. The social satire in the book's four stories targets Peter Gunn-style private-detective shows, Westerns such as Gunsmoke, capitalist avarice in the publishing industry, Freudian pop psychology, and lynch-hungry yokels in the South. Kurtzman's character Goodman Beaver makes his first appearance in one of the stories."--Wikipedia
