That’s Don Zimmer, who managed the Cubs from 1988-91, being interviewed by a Cardinals broadcaster (more on him later) — you can see the Cardinals logo on the mic flag.
If this were the entire photo I wouldn’t be able to tell you anything about the date, all I could tell you was that it was taken at Wrigley Field. Getty Images says it was taken in “the late 1980s” and, well, that’s pretty obvious from Zimmer being interviewed. (Yes, Zimmer was also a Cubs coach from 1984-86, but that position wouldn’t likely have gotten him interviewed by a Cardinals broadcaster.
