Above, an ad for a Washington D.C. Cole dealership–the picture at the top is of Johnson and outfielder Clyde Milan “In their Cole Roadster”:

The second ad, below, is for the local Detroit Electric dealership:

Walter Johnson
and the
Detroit Electric Brougham
Johnson remained on the mound longer than Cole stayed in business; the car maker closed in 1925. Detroit Electric continued building cars until 1939 and the company was revived in 2008.
