death of a salesman

The suitcase symbolizes Willy's job. He's a traveling salesman, and traveling is a part of who he is.

The silk stockings represent power and money. They're expensive, they get attention, and they get women. They also provide Willy with a lot of guilt, as we see him consistantly focused on the state of his wife's stockings. The fling got was intended for his wife, while his wife sat home mending what she had.

The woman with no name respresents unfaithfulness. She was one woman in what was probably a long line of meaningless one night stands. She doesn't have a name because she could have been anyone.... she represented Willy's repeated unfaithfulness.
