Trade cards are small printed cards used by businesses in the 17th to 19th centuries to promote their products and services. Often colorful and illustrated, these cards featured the company’s name, logo, and contact information, making them an early form of advertising. They were typically distributed to customers or included with purchases, helping to build brand recognition. Collectors today value trade cards for their historical significance and artistic designs. Many cards feature images of popular products, local landmarks, or even famous figures from the time. Collecting trade cards has become a hobby, with enthusiasts seeking out rare examples from companies like Coca-Cola or Pepsi.
