An important date in ACME History
A mid-1950s construction worker involved in the demolition of the J. C. Wilber Building finds a box inside a cornerstone. He opens it to reveal a singing, dancing frog (that came to be called Michigan J. Frog,) complete with top hat and cane.
According to the cartoon, One Froggy Night (1955), the box also contains a commemorative document dated April 16, 1892.
