An advertising booklet, also known as a BROCHURE, is a printed document that contains information about a product or service. It is usually used to promote and market a business or organization. Brochures are typically distributed in public places such as trade shows, conventions, and other events. They can also be sent through the mail or handed out directly to potential customers. Brochures are often designed to be visually appealing and informative, with images, text, and graphics that help to explain the product or service being offered.
