We'll participate in one of the year's last events, if not the final one, honoring the 2009 Centenary of the Alaska-Yukon-Pacific Exposition, or AYPE, today, with the authors of three major recent books concerned with this 'first Seattle World's Fair' speak about the AYPE's enduring legacy. Joan Hockaday's Greenscapes: Olmsted's Pacific Northwest (Washington State University Press) is the first full-length treatment of the work of John Charles Olmsted in this region. His many projects include the design of the AYPE site on the University of Washington campus. UW Visual Collections curator Nicole Bromberg's book, Picturing the Alaska-Yukon-Pacific Exposition: The Photographs of Frank H. Nowell (University of Washington Press), features the work of the Fair's official photographer, who documented its construction, workers, landscaping, and visitors. History Link staff historians Alan J. Stein and Paula Becker's Alaska-Yukon-Pacific Exposition: Washington's First World's Fair: A Timeline History (HistoryLink/UW Press) provides a detailed, fully illustrated history of the fair and fairgoers, and of many political issues (women's suffrage) in the air at the time. A lively program, much sharing of the visuals—this should be fun.
