The seal of Chicago is the corporate insignia representing the city of Chicago.
The original seal was adopted in 1837 but was replaced with the present day seal in 1905. The seal represents the authority of the City government, and often conveys to people who see it that they are seeing an official communication, bearing the City's imprimatur.
