On September 30, 1975, COSI revealed their display of U.S. Presidents.
There were 38 presidential replicas at the time. Visitors could learn history and read quotes from each U.S. leader.
The display was set up by Nationwide Insurance, just in time for the U.S. bicentennial in 1976.
The exhibit continued to grow through President Clinton, but it was not transferred to the current COSI location.
