Grizz,
We'd like to WELCOME you to the Original John Wayne Message Board, truly a great place for fans of the great man to gather and converse!
Off hand, I don't know anything about the dressing room marker you are describing, but there's a chance someone here might. Do you have any pictures of it, that you can post here?
Looking forward to getting to know you better,
Chester 
and the Mrs.
