Did the Homer Laughlin China Company supply the Masters Golf Tourney with china?

I have two coffee/tea cups with the notation "bc1136" on the bottom. I know that these are from the "best china" line of Homer Laughlin China Company. What makes these cups unique to me is that they have the Master's Golf Tournament logo on them. The notation on the bottom of the cups also reads as follows: 2-2-99 ok wm c (not sure about these initials) then IG decal. I am simply trying to figure out if HLC furnished cups to the Masters Tournament and if so, what year would these cups have been used. Are they worth anything?
