I have heard that the most famous Undertaker fan in the wrestling business is selling her 20+ year Undertaker collection of action figures, dvds etc. She is known to the wrestlers as Spunky and to fans as The Wrasslin Queen. She is posting her collection on ebay under her username "morgeesroom" or here is 1 of the item numbers - 170699178213.
She is the real deal as the best known Taker fan on the planet. Take a look at her website. Go to morgeesroom.com then click Wrasslin Queen banner. She has a Taker collection to die for. I am gonna try to see if I can get some money to bid on her auctions.
Take a look.
