CHICAGO — WGN-TV’s Bozo show went off the air in 2001 but on Tuesday, the station received a card for “Bozo’s Circus” postmarked August 20, 1977!

It was sent by Sonal Dighe, a 7-year-old girl from Waukegan. She sent the card in to be an at-home player for the show’s “Grand Prize Game.”

Children who couldn’t attend the show would send in cards to be at-home players and if they were selected, they would win the same prizes as the in-studio players.

Do you know Sonal? Please help WGN find her. We’d love to give her a chance to play the “Grand Prize Game!”
