From early to mid-50s although we aren't sure what sponsor offered this very neat premium ring. Adjustable brass bands have large portraits of Howdy and Clarabell on the sides. A brass strap across the top holds silver luster aluminum 1.5" replica of Clarabell's horn. Produces a loud squeaking sound. Trivial silvering loss on the horn but vast majority of luster remains and the luster on the brass base is near 100%. Exc. and quite scarce.
