The Voyeur's Motel by Gay Talese:
As Gerald Foos slowly led me past the cases, he would sometimes pause, take hold of a certain card, and make comments about it.
“Here’s a rookie card of Michael Jordan,” Gerald said, adding that he purchased it as a flea market years ago from an ill-informed trader for only twenty dollars. Gerald then held up a card showing the baseball player Alex Rodriguez and admitted that it had dropped in value in recent years. “Here’s a guy—excuse my English—but he just pisses me off, because if he would have stayed away from steroids he would have probably been the greatest player in the world.”
