The covers are printed on a variety of colored 100-lb. cover stocks from the French Paper Company of Niles, Michigan, using a custom, five-color process that started with under-printing white ink. The illustrative styles, the printing process, and the copper staples recall the heritage, and archival promotional materials and publications, of the National Park System. Series A includes Yosemite National Park and Zion National Park, both by Dan McCarthy, and Acadia National Park by Telegramme Paper Co.
