This listing has 5 dealer promotional movies and two brochures. The brochures are the 1974 el Camino and 1974 vans both are in very good condition. The van brochure staples are rusty otherwise really clean. The movies are untested and a bit dirty/dusty but I don’t want to clean them for fear I will cause damage. They came from a local estate.
