Here is an odd ball offering! Very cool with great colors and a Dynamic Slot Car History! This Listing is for AN UNUSED ROLL of Vintage Factory Dynamic Models Inc. Cardboard PARTS HEADER CARDs measuring 2x3" each. They were used for parts sold in the 1960's. "Quality Model Products Van Nuys, California." Made in U.S.A. It is exceptionally odd to find advertising packaging header card surplus that is almost 50 years old! Use for track or room display, cut it down to create original vintage Track Side Bill Boards using simple side by side plastic clips sold elsewhere. They look great folded over and set up in an A-frame sort of berm! I can do custom lengths if requested. These are from original equipment distributor overstock, and are guaranteed to be original and sparkling clean too!
