Correct me if I am wrong. Are you talking about this passage which I share below?
(We stopped before a summary display window
at Macy's, The World's Largest Department Store,
to admire a family outfitted for the beach:
the handsome father, slim and sure of himself)
If so, the family in the display window at Macy's symbolizes the ideal American family, that's for sure. Hope you still need it, because it's really useful answer.
