A sandwich board is a type of advertising display that consists of two connected boards, often made of wood or metal, that stand upright on the ground. It is typically used by businesses to promote products, services, or events. The boards can be easily moved and placed in high-traffic areas, making them an effective way to attract attention. Sandwich boards are often seen outside restaurants, shops, and events. They can be customized with colorful graphics and messages, allowing businesses to convey information quickly. This form of advertising is cost-effective and can be changed frequently to reflect new promotions or offerings.
