Durango to Silverton     Narrow Guage in Colorado and Colorado's Centennial.     Four panel brochure and timetable of the famous Durango to Silverton Narrow Guage Line.      Brochure provides a brief history of the narrow-gauge lines in Colorado along with a map and schedule of trains.    No date but since it references Colorado's Centennial Year, I would place it as 1976.     3 1/4" x 5 1/2" unfolds to 13" x 5 1/2".     4 panels.    Shipping via First Class Mail.     I will consolidate orders, if requested to save on shipping charges.
