In 1922, Luigi D’Andrea invented the first plastic guitar pick in NYC by repurposing cellulose nitrate sheets, inspired by his son, and pioneered mass production as the "Henry Ford of guitar picks." His son Anthony and grandson Tony Jr. innovated manufacturing, marketing, private labels for top brands/artists, new gauges, and printing, amassing 25,000+ imprint files. D’Andrea USA remains a global leader in custom picks and accessories.
