1885 Chicago Opening Day Baseball Program

"Cap" Anson, Billy Sunday, Michael "King" Kelly ... some of the very first baseball legends, and they're all here. Check out this slideshow of a rare souvenir program from Opening Day 1885.

At the June 20, 2007, appraisal event in Baltimore, a guest named Kathy brought in this old Western Union envelope, marked "Chgo. Balll Team 1885" in her great-grandfather's handwriting. Inside it was a well-preserved, 120-year-old souvenir program from Opening Day that provides a remarkable glimpse into the very early years of professional baseball.
