The Ohio Mechanics Institute (OMI), founded in 1828, is one of the College of Engineering and Applied Science’s (CEAS) source institutions and provided vital technical education during the early development of Cincinnati. In 1870, OMI partnered with the Board of Trade and Chamber of Commerce to present the first “Grand Industrial Exposition.” These showcases attracted exhibitors nationwide representing industrial developments and artistic achievements of the day. 

Commemorative tokens from the expositions were adorned with visual reminders of the events. Many of the tokens feature the buildings that housed the exposition, such as the Saengerfest Hall, a structure that sat at the intersection of Elm and 14^th streets. Other common symbols found on tokens represent the industrial exposition subjects: agriculture, science, art, and learning. 

A sampling of these tokens are currently on display in the CEAS Library.
