Many baseball card blogs from our hobby's history cover the full, eccentric range of 1973 Topps photography. Many card shots originate from spring training, with chain link fences galore. While Topps picked a few bad apples, they also found some great ones. Based on box score research, I think #273 Chris Speier shows baseball's most exciting play, an inside-the-park homer, from July 15, 1972. Catcher #6 John Bateman sprawls in the dust and Phillie relievers look on from their left field bullpen. (Those empty box seats reflect the poor midseason records for both teams.)
What's more, Speier faced off against peak Steve Carlton, during the Cy Young winner's mid-season streak of 15 straight wins. The two-run scamper put SF in front 4-0 and would be the most runs Carlton allowed all month. Despite Steve's departure after five innings, Philly found victory by scoring 11 runs in their top of the seventh, creating this 5% to 99% win probability cliff.
11 runs set Philly's high water mark for any 1972 game, let alone for one inning, and Topps benefited from a shot of Speier's standout play. Oh, for another 100 in that set anywhere near as good!
