GlennAndrew,
That card is from the 1925 Holland Creameries or "Holland World's Champions" set depicting the Senators team that won the 1924 World Series. They were issued in Winnipeg, apparently in very small quantities. I've owned two of them (Zahniser and Ogden) but have sold both to board members.
