The 1966 World Series matched the Baltimore Orioles against the defending champion Los Angeles Dodgers, with the Orioles sweeping the Series in four games to capture their first championship in franchise history. Despite the general consensus that the Orioles were short of pitching when compared to the likes of Don Drysdale and Sandy Koufax, Orioles pitching allowed only two runs in the entire series and ended up with a 0.50 team ERA, the second lowest in World Series history. The Orioles scored more runs in the first inning of the first game than the Dodgers would score in the whole series.

This 1966 World Series program has only a little wear around the edges but no rips or creases. It is unscored.
