In what has become one of my favorite traditions of each major championship week, some of the big equipment companies are rolling out limited-edition gear to mark the occasion. No one does it better than TaylorMade, which has created a special bag and headcover for the 2013 PGA Championship  with an Oak Hill theme. The photo on the left is the headcover on the bag of Roberto Castro, and I included it here because it shows off the logo so well.
The logos on the TaylorMade gear are always intricate, and full of detailed iconography. Here, courtesy of TaylorMade, is the full explanation of every aspect of the 2013 PGA Championship logo:
--Oak Hill Country Club is located in Rochester, N.Y., the home of Frederick Douglass, the American social reformer, orator, writer, statesman and abolitionist who escaped slavery as a young man. Douglass lived in Rochester from 1847 to 1872 and is buried in Rochester's Mount Hope Cemetery, and the logo's shape was inspired by a part of his tombstone. The star at the top of the logo represents The North Star, the famous anti-slavery newspaper Douglass founded in Rochester in 1847.
--The trophy image represents the Wanamaker Trophy, named for Rodman Wanamaker, a department store magnate who in 1916 hosted the exploratory meeting of the Professional Golfers Association, at which the idea for the PGA Championship was conceived. Wanamaker also provided the trophy for the first championship, which is still used today.
--The yellow-colored honeycomb pattern is a nod to the YellowJackets, the name of the University of Rochester's athletic teams. Oak Hill swapped the land it was originally located on with UR, giving the country club a piece of land large enough to eventually build two 18-hole courses, the East Course and West Course, the former of which has hosted U.S. Opens, a Ryder Cup and three PGA Championships (including 2013).
--The six oak leaves refer to the six different prominent tournaments that Oak Hill has hosted during the past 60+ years, including the U.S. Open, PGA Championship, Ryder Cup Matches, U.S. Amateur, U.S. Senior Open and Senior PGA Championship.
--The plaque with 2013 on it is a nod to Oak Hill's ''Hill of Fame,'' a series of bronze plaques located on the hill leading up to the 13th green, which are emblazoned with the names and faces of numerous golf luminaries, including past winners at Oak Hill.
--''Gloria Ultimus'' is Latin for ''Glory's Last,'' a reference to the nickname the PGA of America has given to the PGA Championship, ''Glory's Last Shot,'' which alludes to the tournament's position in the schedule as the last Major Championship of the year.
--R stands for the last name of the East Course's highly respected architect, Donald Ross; W stands for the last name of Dr. John R. Williams, the member who, in 1926, planted tens of thousands of oak trees on the grounds.
