Pull My Tail" Pig Transformation Advertising Plows to Farmers

South Bend, Indiana: The Economist Plow Company, 1880. Very good. Toned, a little dust soiling to back.. An amusing transformation die-cut in the shape of a pig, with the directive "PULL MY TAIL". When the pig's tail is pulled, a printed slip is revealed to advertise "Solid Comfort" brand riding plows to farmers. Measures approx. 3" by 6" closed, 3" by 7.5" open. Lithographed card mechanism secured with twine on back. Pig "tail" made from about an inch of thicker twine.
