The entire Loman family places heavy value on appearances and good looks. Many of Willy's fondest memories of Biff involve his son dwarfing others with his personal attractiveness. In addition, when Willy gives in to feelings of self-doubt, he worries that it's his appearance that's holding him back in business. Death of a Salesman may be making a larger statement, by showing the Lomans' fixation on attractiveness over real substance. Could the play be trying to get across the idea that all of America falls prey to the very same mistake? What do you think? Is America itself way too obsessed with image and appearance?
Biff’s dedication to keeping up his appearance suggests his remaining desire to impress his father.
