Edit: The name was "Witchdoctors Club" - without the apostrophe...
i have a copy of the by-laws written by Clayton Rawson. The membership card has a W with Club sign in the corner. A card is the collections of magicians Jeff McBride, Alex Stone, and Jen Kramer. I know because i gave the cards to them. Clayton Rawson, Jr. aka Tgmerlini
Name fixed: Thanks!
