'64 was the first year I was a Reds fan. Geeky 12 yr. old with his white plastic AM radio with Waite Hoyt and Claude Sullivan. And Ed Kennedy and Frank McCormick on WLW-D. What a year to break in on.
What it looks like to me is the Cardinals are the Phillies, the Astros are the Reds, and the Reds are the Cardinals, i.e. in 1964 the Phils had the big lead and blew it, the Reds breathed down their necks that whole collapse, and the Cardinals came out of nowhere and snuck in at the wire.
Pay attention to the open sky
