July, 1978 Chevrolet Dealer Truck Action Programs [Traction] Sales Folder. These were sent to Dealers to help them with Truck Advertising and Promotions as well as giving Salesmen Model Information and Promotional Techniques and Ideas. This Folder has Tecovan Box Truck and other materials [see photos for contents and condition]. Very informative and cool display item for the Chevy Truck Owner or Collector.
