Answer: How is Jerry able to obtain one of the highly desirable Grover Cleveland cards? He trades someone who lives on the Northside for one. He trades Rollie Tremaine for one. After selling the card to Rollie Tremaine, Jerry gives the money to Armand. This act shows that Jerry has matured and learned that helping his family is far more important than helping himself. Twelve-year-old Jerry must decide whether to use his collectible "Grover Cleveland" card to win a contest or sell the card so that his brother can take his g to the school dance.
