The Colonial was an American automobile that was manufactured from 1920 until 1921.
The car was built in Chicago, Illinois, and was nothing more than a Shaw with the emblem switched; it was, however, treated as an entirely separate marque. In 1921 the company returned to using the name "Shaw" for its vehicles; soon thereafter, the entire operation was sold to the Yellow Cab Company, which renamed it "Ambassador".
