The Shadow Club membership kit includes an illustrated mailing envelope, a pinback button with "The Shadow Club" in green over black, a membership certificate, issue #1 of the newsletter "The Shadow News", a secret code card, an "autographed" movie still of The Shadow, a gold metal Premium Ring embossed with the 1994 movie logo and club name and a Special Agent card, individually numbered on the back. I own two complete kits, the one in the photo is #01138.
You can find more information on "The Shadow Sanctum" website.
