Hard-to-miss signs are a type of signage that is designed to be highly visible and eye-catching. BANNERS and neons are two common examples of hard-to-miss signs. BANNERS are large fabric or vinyl sheets with words or images printed on them, often hung from poles or buildings. Neons are signs made of glass tubes filled with gas, which emit light when electricity is applied. Both BANNERS and neons are used to attract attention and advertise products or services.
