Last Career Homers on This Day - Great Things Which is Why They Got a Few Kellogg's Cards

On this day in 1971 Mr. Cub hit his last career homer - #512.   I don't think that I ever was at a game where he homered.  Banks hit 290 at home and 222 on the road.  He only hit seven coming off of the bench.

Banks hit only one homer against the Expos.  Does anyone know why?

Bill Freehan hit his 200th and last career homer on this day in 1976.  Amazingly, Freehan hit exactly 100 at home and 100 on the road.  He hit none off the bench.

Freehan hit two of his homers on artificial turf.  Where would that have been?  Don't count Comiskey Park where they had turf on the infield for a while.
