Adventure Comics #143

At a meeting of the Smallville High School Student Council, Clark suggests they form a school bank. The principal agrees as long as they get Superboy as treasurer. Clark is given the honor of making the first deposit. To solve the problem of being two people in the same place he has filmed himself in costume welcoming himself as Clark. He gives out loans to a number of students, then helps them to succeed. His biggest success lies in getting students to invest in U.S. Savings Bonds.
