The 1908 Spalding Guide
The 1908 edition also promised:
“The origin of base ball settled” with the guide’s “exclusive” publication of the Mills Commission report.
The guide also included interviews with the members of the 1907 Chicago Cubs, on “How we Won the World’s Championship.”
The ad featured part of the interview with right fielder Frank Schulte, who used his World Series money to buy a racehorse:
“I was far from pleased with my own work, but there were spots that seemed bright, and so I have no misgivings about spending my share of the winnings for a great piece of horse-flesh…”
Frank Schulte
Other comments from members of the Cubs that appeared in the guide included:
Joe Tinker—“We failed to see that brilliancy that the American League boasted of, and when the good old West side machine got under way, it seldom failed.”
Orval Overall—“I expected a harder time with the Tigers.”
Orville Overall
Mordecai Brown—“Never more confident of victory in my life. I almost made a hit in my three times at bat.
Jack Pfiester (who won game two 3 to 1 while giving up 10 hits)—“After the two base hits in the first inning, I knew by some overpowering sense that I could not explain that I would be successful.”
