JOHNS CREEK, Ga. — The folks at Taylormade who construct the company's symbol-filled commemorative logos pulled out all the stops for the 2011 PGA Championship. Here is a cheat sheet to help you decipher it.

　　The curls and lines of the logo itself are meant to be in the Art Nouveau style that was popular when the Atlanta Athletic Club was founded in 1898.

　　The last major championship played here was the 2001 PGA Championship, won by David Toms. The "265" at the top of the logo represents his winning score.

　　In the center of the logo is a four-leaf clover with an "02" in the middle. This is a tribute to Bobby Jones, whose statue sits in front of the Atlanta Athletic Club's clubhouse. He was born in Atlanta on St. Patrick's Day in 1902.

　　During Jones's career, the U.S. Amateur and British Amateur championships were considered majors, along with the U.S. Open and British Open. He won 13 of those events, and if you look carefully you'll count 13 rays emanating from the four-leaf clover.

　　Jones retired from competitive golf in order to pursue a legal career at 28. Stamped onto TaylorMade staff bags is the image of a scale, which represents the Scales of Justice.
