From early to mid-50s although we aren't sure what sponsor offered this very neat premium ring, however we suspect Colgate-Palmolive. 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. There are some very tiny marks on the brass strap but really just showing on closest viewing. Brilliant NM luster on both the horn and base. Scarce and especially so this nice.
