Not many people take time to notice the top of the haunted mansion as I have. Having perched on top of there many times to watch the foolish mortals enter the house i noticed something of a reoccurring signature in wdw by my personal friend Marc Davis. Although the imagineers are forbidden to sign their work some leave little clues. Marc Davis had a love for the game of chess and left pieces in his work. You may have also noticed these with a keen eye but for those who wish to see notice the clear chess pieces sitting on top of the mansion or perhaps the" never ending" chess game between our swashbuckling friends in the queue over at pirates of the Caribbean.
