Here's a Lon Chaney Ring-portraying his classic 'Phantom of the Opera' role-that's about it.No marks,pot metal/perhaps steel/adjustable by squeezing the finger portion of the ring.All else unknown-can't find any Web info-not a gumball Flicker Ring from the '50's-60's.Iconic image,role,movie-it's a mystery to me. Thanks For Any Help-Bosko
