3x5.5" mailing envelope w/"The Shadow" illustration and D.L. & W. Coal Co. return address and typed recipient name/address. 2.75x4.25" Heavy wear w/crease and tears w/some small archival tape repairs. Missing right end flap. Just comes along but rare. Double-sided paper has detailed instructions while back is an unused order form for additional rings that were available for 10¢ apiece. Both sides feature Shadow images, front text includes "You Are Now A Member Of The Shadow Stop-Crime Club." All over creases and general wear. Good and also rare. Glow-in-the-dark plastic ring has simulated blue coal lump on the top while the bands depict The Shadow w/gun and "The Shadow - Blue Coal" names around top rim edges. Ring shows slight age but still glows brightly. Exc. We have only offered a few examples complete w/envelope and paper in our 58 years. Robert M. Overstreet Ring Collection.
