That's a view looking west along Addison, about seven blocks west of Wrigley Field, at the new L station on the CTA's Brown Line.
The little squiggles on the brick are art. Yes, art. They are, according to chicago-l.org, "Ron Santo's handwritten box score symbols describing the May 14, 1969 Cubs-Padres game".
OK, first, take the leap of faith that Ron Santo actually scored that game -- either then, or years later. In any case, check out the boxscore and play-by-play from that game. The Cubs won that game by scoring two runs in the bottom of the 9th -- here's the PBP from that inning:
Banks homered; Hundley flied out to right; N. Oliver doubled to right; Phillips was walked intentionally; REBERGER REPLACED PODRES (PITCHING); W. SMITH BATTED FOR HICKMAN; W. Smith singled to left [N. Oliver scored, Phillips to second]; 2 R, 3 H, 0 E, 2 LOB. Padres 2, Cubs 3.It appears they put the PBP reading from bottom to top, instead of top to bottom, as you'd usually read it on a scorecard. Click here for a larger version of the photo above.
