Marquee

A Marquee (also know as a letter board or letter sign) is a customizable form of signage that employs individually movable letters of the alphabet.

Most commonly placed over the entrance to a hotel, theatre, casino, train station, or similar building, they are used by movie theaters to list the current roster of films, churches to display the titles of sermons, and other buildings, people, and institutions whose signs are required to change on a regular basis.

The marquee is sometimes identifiable by a surrounding cache of light bulbs, usually yellow or white, that flash intermittently or as chasing lights.
