There are two different items on this site.
First is the Dedication pamphlet which was passed out to all who attended the dedication and contains a brief overview of the features of the facility.
Second is the KCS Newsfolder from June 1956. The Newsfolder has a lot more detailed information as well as a lot more people pictures in it but also has a number of duplicate photos from the dedication pamphlet as well.
