Bill Clinton Shaking Hands With John F. Kennedy (1963)

Despite being presidents nearly three decades apart, there was a time when Bill Clinton and JFK shook hands, as captured by the photograph above.

Still a student in high school, the Arkansas government selected Clinton as one of two delegates to the Boys' Nation- a program that has been running since 1946 and brings students to Washington D.C. to participate in a week-long seminar.
