An 1884 candy trademark — when sweetness became paperwork.
Darby & Co.’s registration shows how American confectioners began fixing flavor into identity, mark, and memory.
thepalimpsest.nostalgicconfections.com/orphicon-dar...
An archival document from 1884 showing a trademark registration filed by Darby & Co. of Baltimore, Maryland. The aged paper features a centered design with a diagonal red-and-white striped candy cane and an ornate “D&CO” monogram. Text indicates registration for “Stick Candy, Cakes, Drops, Balls, and Dice,” along with the weight marking “5 Pounds,” suggesting bulk commercial distribution. Handwritten notations, official stamps, and legal signatures appear around the margins, situating the document within U.S. Patent Office trademark records. The image reflects early efforts by American confectioners to formalize branding, visual identity, and product recognition in the late 19th century.
