Description
Black and white 4″ x 6 1/2″ ad for their combination Twin-Thirty Lawn Mower and Roller. The ad has a picture of a man taking care of both jobs on his lawn at the same time as the headline asks you to “Investigate the Coldwell Better Lawns at Less Expense”. The claim is made that using this machine a person could mow and roll simultaneously 6 to 8 acres a day on one gallon of gasoline.
