This is a vintage 1980's Iron Maiden Killers one inch round metal enamel lapel or hat pin. It is made with a gold colored metal, with a black background and then very detailed yellow gold and red to make the zombie character from the Killers album. Iron Maiden is in red lettering.

I purchased these from a large lot of vintage unsold 1970's/1980's concert pins, pendants, and necklaces. The person selling them said he used to be a promoter and had leftovers from concerts that he put in a box in his garage and forgot about. These lapel pins look brand new, but have no branded packaging.
