In honor of the History Colorado Center exhibition Play Ball! A Celebration of America's Game, enjoy an issue's worth of Colorado baseball's storied past. In the cover story, Senior Curator Alisa DiGiacomo shares rare photos of the state's early amateur and semi-pro teams, many of the images from the collection of preeminent baseball historian Jay Sanford. In other stories, meet the women who barnstormed the state in "Bloomer Girls" teams, and learn how History Colorado is collecting the memories and memorabilia of those who brought major league ball to our state.
