Original 1929 Ford Tri-Motor Airplane Ad Proof. This Ad Proof would have been sent to Ford by the Magazines or Papers that ran this Ad, one of which was Vanity Fair. It touts the increase of Airports in the Country. It is in good condition with minor wear and soiling [see photos]. It is printed on slick paper and is creased across middle from being folded in half. Very rare piece that will make a cool framed display item.
