Theater sign

Quick answer：

A theater sign is a visual indicator or display typically found outside a theater or auditorium, indicating the name of the venue, the title of the performance, and sometimes the date and time of the event. These signs are important for directing audience members to the correct location and for promoting the event. They are often designed to be visually appealing and can vary in style, from traditional to modern, depending on the theater's branding and architectural design.
