Trans-Lux was a company that specialized in rear-projection systems for stock exchanges and movie theaters. With the theater business in trouble at the end of the 1950s, Trans-Lux diversified into television production and distribution; they commissioned the 1960s version of Felix the Cat, as well as The Mighty Hercules. Trans-Lux also brought Speed Racer to the US, commissioning an English dub and handling the US distribution rights. They also had the distribution rights to a few movies, such as The African Queen. Trans-Lux closed the TV syndication division in 1969, selling its animated shows to Alan Enterprises; with the exception of Speed Racer (whose rights have since reverted to Tatsunoko Production, the anime's original producer), all of the Trans-Lux cartoons are now owned by DreamWorks Animation through DreamWorks Classics. The African Queen was eventually relicensed to Viacom Enterprises, who sublicensed it to Magnetic Video, CBS/Fox Video and 20th Century Fox Home Entertainment in the 1980s and 1990s for VHS releases; Paramount now controls the US rights to the film (under license from Horizon-Romulus, the original producers), and handles home video distribution. Trans-Lux itself is still in the display and signage business.
Visuals: It has two variations:
Technique: Cel animation.
Audio: Also has two variations:
Availability: Can be found on DVD sets of the 1960s Felix the Cat series. While the beige/blue background variant was spotted on old TV airings from the 60s to the 80s (even international), modern copies of the series and DVD prints only have the initial "Righty-O!" title, which also replaces the secondary one on the episodes that originally had it (likely because of the poor condition of the film elements).
Visuals: There is the word "TRANS-LUX", in large, sans-serif letters, styled similar to the THX logo, with the bar on the T and the tail on the "S" extended to outline "TRANS", the lower bar of the "L" in "LUX" extending into an underline, and a bar over "LUX" that touches the top right part of the "X".
Variants:
Technique: Either a still cel sheet or superposed.
Audio: None or opening and closing theme of the show.
Availability: The English dub of Speed Racer used to be a source for this logo, but newer prints struck in the 1990s remove all mention of Trans-Lux. It's also been spotted on old Magnetic Video prints of The African Queen, and on episodes of Mack & Myer for Hire on Decades.
