Vintage Star-Over-Disk Enamel Lapel Pin

This is a circular lapel pin or button consisting of a bright yellow plastic or enamel base disk measuring approximately 20-25mm in diameter. Mounted centrally on the disk is a metallic four-pointed star with a textured finish, likely brass or gold-plated base metal. The star features deep linear embossing or ribbing on each point, converging towards a central roundel. This central roundel is finished in a translucent blue enamel, showing a metallic horizontal bar element beneath the surface, which gives it a 'cat-eye' or jewel-like effect. The coloration suggests mid-century manufacturing, likely from the 1960s or 1970s, often associated with company service awards or fraternal organizations. Regarding condition, the metallic star shows moderate oxidation and loss of plating along the edges and raised surfaces, revealing a darker patina underneath. The yellow base appears relatively stable but has minor surface micro-scratches consistent with age and use. There are no visible maker's marks on the face. The craftsmanship is of a commercial grade, utilizing mixed media (metal and polymer/enamel) to create a high-contrast aesthetic. The blue enamel center remains intact without significant chips, preserving the depth of the center motif.
