Getty Images says:
Juan Samuel #8 of the Philadelphia Phillies slides into second base safe against the Chicago Cubs during a Major League Baseball game circa 1984 at Veterans Stadium in Philadelphia, Pennsylvania.
The infielder identifiable in this photo is Dave Owen, who played for the Cubs from 1983-85. All right, now we have a date range that includes what Getty said in its caption.
Owen played in eight games against the Phillies at the Vet during his Cubs career, all in 1984 and 1985. Three of those games were night games, and this is obviously a day game.
