Death of a Salesman, by Arthur Miller. 13. Charley says, "The only thing you got in this world is what you can sell. And the funny thing is that you're a salesman, and you don't know that." Miller says that when asked what Willy was selling, he could only reply, "Himself." What is in Willy's bags that he takes to the buyers to sell? For what region is Willy responsible in his sales?
