As you read in an earlier WHG blog [11], the Stock Show is taking place until the 22nd of January. You can read more about it here [12]. WHG has several collections that include Stock Show documents and memorabilia.
The National Western Stock Show records (WH940) [13] include newspaper clippings, scrapbooks, tickets, buttons, programs and other memorabilia from past shows.
Nicholas Petry, once chairman of the Stock Show, has a collection [14] at the library which includes photographs, clippings, scrapbooks and more.
Walter Orr Roberts [15], who helped establish NCAR, discusses the Stock Show in his oral history.
Try searching for the words “stock show” in the Denver Public Library catalog [16] for much more.
