Description
Full color 7 1/2″ x 10 1/2″ ad for their well-known Mufflers. There are two pictures in the ad, the first shows a Thrush muffler just out of the box with the caption saying “Put this on your pipe…”. The picture below shows the rear tire area of a red car whose red-wall tire is spinning on the pavement with the caption saying “and smoke it”. The text describes the thrill of completing the installation of a Thrush muffler onto your car, starting it to marvel at the new sound and driving around to enjoy the looks of the people as they respond “What the devilwuzit?”.
