This ring is one of four Cap'n Crunch plastic rings issued in the 1970s. The other three that were pictured on the package include Guided Missile Ring, I-Spy Glass Ring, Carlyle's Rocket Ring (with shooting missile). This particular ring promotion text on package read "Leave It To Brunhilde To Have A Real Top-Fashion Ring. In Fact, It Is A Top. And A Whistle...It Also Has A Secret Compartment." The ring is done in dark green plastic in four separate pieces which must be disassembled to perform some of their functions but when assembled as a single unit the ring is a very impressive 3" tall in height. The ring includes a full figure of the character with both her pigtails and arms and hands extended. Only marking is on the underside of the secret compartment as "Made In U.S.A." Only example we have seen and NM displaying Mint. Rare.
