From Charles Leerhsen's biography “Ty Cobb: A Terrible Beauty”:

But for whatever reason the 1907 World Series went about as badly for Detroit as things would go for Butch Cassidy and the Sundance Kid down in Bolivia a few weeks later.

I guess I knew this. I certainly knew Cobb began his career in 1905, and I knew that Butch and Sundance lasted into the 20th century, but the juxtaposition of the two (or three) is still somewhat startling.
