The Birmingham Barons, Double-A affiliate of the Chicago White Sox, hold their 17th annual Rickwood Classic on Wednesday afternoon -- with this year's theme being baseball during World War II.

Check out Playbook Fandom's story on the special day, played inside baseball's oldest active (for a day) ballpark. Then check out these commemorative posters, courtesy of Friends of Rickwood.
