The Stevens Treaty Council of 1855 Centennial Celebration Records, which dates from 1954 to 1956, contains not only the program for the weekend long event, but also a collection of the speeches delivered during the commemoration. Speakers included a representative of the Bureau of Indian Affairs and Nez Perce, Yakima, and Confederated Tribes representatives. A draft and final copy of Bill Gulick's pageant script and a transcript of a witness's narrative of the 1855 Walla Walla Council are also housed in this collection. The Correspondence file consists primarily of invitations to and responses from dignitaries invited to attend the event. Correspondence and memos from event planners may be found in the Miscellaneous, Luce Memorandum, and Supporters and Tribal Organizations files. Newspaper clippings about the event and the publicity file provide information about the dissemination of information about the event and its reception. A file on the "Sacajawea of 1955" contest rounds out the collection.
