(September 14, 1957-)
Logo: On a black background, we see the text saying "THIS PICTURE MADE UNDER THE JURISDICTION OF", with the IATSE print logo in the middle of the screen. The text under the logo says "AFFILIATED WITH A.F.L.-C.I.O.-C.L.C."

Variants:
 * On TV series, the length of the logo would vary, from an actual production company logo's length, to where you will miss it if you blink.
 * On the first episode of the 2021 Gossip Girl reboot, the logo appear to be upside down.
 * At the end of practically every film, the logo scrolls up with the credits, normally beside the Motion Picture Association's logo.
 * On Hanna-Barbera's 50th: A Yabba Dabba Doo Celebration, the logo is under the text of the Hanna-Barbera logo from 1979-1990.
 * On The Tracey Ullman Show Backstage, the logo is superimposed over the 1981 20th Century Fox Television logo, along with said company's copyright stamp and the AMPTP logo.

Technique: None.

Music/Sounds: The ending theme of the show/film or silence.

Availability: Uncommon in TV shows, but ultra common in movies. It can be seen at the end of practically every film and various shows produced in the U.S. and Canada. One of the first shows/movies to use this logo is Have Gun, Will Travel.

Legacy: This logo is the oldest logo currently and continuously used on the wiki with a verifiable introduction date, although most of its uses basically boil down to in-credit notices.
