These 7 cards are from 4 different courses.  When opened, the 3 Northville Goif Club (all of which have scores inside them) and 2 Brae-Burn Golf Club cards measure 6" in length and could be used as stymie measures.  The Bloomfield Hiils card has a stymie measure printed on the inside along an edge. The American Golfers Club score card is not a stymie card, but it has been signed by Julius Boros.  The course at the American Golfers Club course was designed by Robert Trent Jones and is a par 58.  According to the card, "mens course measured from the ball washer to the center of the green."
