"Heavy Metal" eagle / flying V vintage crystal pin.
It comes from a 1980s private collection, it's in a very good condition as per pictures.
Butterfly clasp fastening.
Not sure about the origin of this one. The logo looks a bit like the one of the 1981 film, but not that close either. It's probably just a slogan pin - any info' about it is very welcome.
Dimensions: approx' W 2,3 cm x H 2,3 cm.
