With the Calgary Stampede celebrating its Centennial in 2012, the Calgary Herald delved into the past, present and future of this event -- the Greatest Outdoor Show on Earth. The result is a book brimming with treasured stories; with hundreds of rare and/or historical photos; the 10 most unforgettable Stampede images from each decade of the past 100 years; pages of memorabilia; a collection of the Stampedes annual posters; and archived editorial cartoons. Also found in this book are chapters exploring ten major themes of the Stampede; stories and photos from the Centennial event itself; a reproduction of the rare program from the first Stampede in 1912 (complete with pictures and text); and writings from Stampede founder Guy Weadick before his death.
