A sharp-eyed boy who collects antique radios is taking umbrage with the vintage radio on display inside gangster Al Capone's cell at a historic Philadelphia prison, reports the AP. Eastern State Penitentiary closed in 1971 and now operates as a museum and national historic landmark. Thirteen-year-old Joey Warchal took a tour and noticed the radio in Capone's cell was wrong: The Prohibition-era mobster spent time at Eastern State in 1929 and 1930, but the radio was made in 1942.
The seventh-grader offered to find the prison a historically accurate radio, and the prison gladly accepted his help. The Philadelphia Daily News reports the teen has located a 1929 model and will deliver it to Eastern State next week. Joey began collecting at age 8—his mom says that while most kids want toys, "he wants antiques." (More Al Capone stories.)
