Advertising Hoarding, also known as a BILLBOARD, is a large outdoor sign used to advertise products or services. It is typically placed in high-traffic areas such as highways, streets, and public spaces. The size of the BILLBOARD can vary, but it is usually large enough to be seen from a distance. Billboards are often used to promote businesses, events, or campaigns. They can also be used to display messages about safety, politics, or other topics.
