This is a fascinating collection of most known trailer firms & their (original) brochures & catalogs from 1930 to 1950. The CD is loaded with 87 brochures with floor plans, pictures, specs, etc. Many super, rare brochures from the early years! Note: If you are interested in information about Airstream, Avion, Boles Aero, Silver Streak, Streamline or Spartan trailers, please purchase the Silver Beauties CD instead of year-specific brochure collections.
