A production logo, vanity card, vanity plate, or vanity logo is a logo used by movie studios and television production companies to brand what they produce and to determine the production company and the distributor of a television show or film.
 Production logos are usually seen at the beginning of a theatrical movie or video game (an "opening logo"), or at the end of a television program or TV movie (a "closing logo").
 Many production logos have become famous over the years, such as the 20th Century Fox's monument and searchlights, Paramount Pictures' mountain, Universal Pictures' spinning globe, Warner Bros.' shield, Columbia Pictures' personification of Columbia, MGM's Leo the Lion, and Walt Disney Pictures' fantasy castle.
 Unlike logos for most other media, production logos can take advantage of motion and synchronized sound, and almost always do.
