Enamel lapel pin depicting a stylized character with dark skin and red lips.

Lapel pins, also known as enamel pins or badge pins, gained significant popularity as decorative accessories and collectibles throughout the 20th century. They are often used to express affiliation, support for a cause, or simply as a fashion statement. The use of enamel allows for vibrant colors and detailed designs, making them attractive to collectors.

This particular pin, with its stylized depiction and bright colors, likely originates from a period when such novelty items were common, possibly for events like carnivals or as merchandise for performers. The reference to Serge Gainsbourg, a prominent French singer-songwriter, suggests it might be related to his persona or a specific performance, though the depiction is quite generic and could also be a carnival character.
