Original 4 x 2.5 membership card for The Society of American Magicians, June 1926, signed 'Houdini,' certifying that W. Paul Koch is a member of the organization. Signed by Houdini as president of the society. Matted with a great photo of Houdini posing with irons, to an overall size of 14 x 20. In very good condition, with wear and soiling to card (probably from being carried in a wallet) and signature a shade light but totally legible. RRAuction COA.
