You young’uns might not recognize both the men in this photo, but to those of us who grew up in the 1960s, we all instantly know Lloyd Pettit and Jack Brickhouse, who shared WGN-TV’s Cubs broadcasting duties during that decade. Pettit was also the voice of the Chicago Blackhawks on WGN-TV through 1970.
I found this photo here, a brochure titled “The Wonderful World of WGN,” obviously created to help market the station’s various broadcasts. It mentions many shows and personalities connected with the station, but there’s no date, so no clue there.
You can see the Astroturf cover on the center field hitters’ background.
