This button is a souvenir from the Chicago International Livestock Show. It is not obvious which year it is from; the show was celebrated by swine, sheep, cattle, and horse exhibitors from 1900 to 1975 at the International Amphitheater next to the Union Stockyards. The International Livestock Show was created to bring the best animals into one area to both raise market value of livestock and educate the agriculture community in how to breed and market their animals better.
