Warner Auto-Meter

Description (Brief)
Advertising card for the Warner Auto-Meter, a combined odometer, speedometer, and clock. The front has image of an auto-meter and black and red print. The back is marked "MEMORANDUM" and is otherwise blank.
The Warner Auto-Meter differed from similar products in its use of magnetic principles for measuring speed. Competitors' instruments utilized centrifugal force to obtain this measurement and were subject to increasingly innaccurate readings as the many parts necessary for this reading wore down or failed. By comparison, the simplified design of the Warner Auto-Meter was much more dependable and long-lasting. The Warner Instrument Company was the first to produce a single instrument for measuring both speed and distance.
