Sunset Productions

Background
Sunset Productions was a subsidiary of Warner Bros. that licensed the TV distribution rights to their black & white animated short subjects to Guild Films in 1955. Seven Arts acquired these rights from Guild after the latter went bankrupt in 1961, and WB gained these rights after merging with Seven Arts in 1967.

Logo (1955)
Visuals:
 * Opening: On a "sky" background, cut-outs of the following characters are shown: Porky Pig, Daffy Duck, Bozo, a rabbit from Hop and Go, the drunk dog heckler from Shake Your Powder Puff, and an alley cat from Sittin' on a Backyard Fence. On the bottom, "Copyright (year) by SUNSET PRODUCTIONS, Inc.
 * Closing: The same image, but the words "THE END - A Guild Films Presentation" appear instead of copyright information.

Trivia: The roman numerals used for this logo are incorrect, as the first "X" should be a "C".

Variant: At least two different redrawn colorized versions of the logo exist, with one having a red background and the other having a green background.

Technique:
 * The whole logo is basically a still frame, the characters seen in the logo are ripped from lobby cards of their respective cartoons, while the background is likely a live-action photograph.
 * For the redrawn colorized version, it is done on a cel sheet.

Audio: The opening theme of the cartoon.

Availability: Since this was mainly used to cover up the Warner Bros. references (including the zooming WB shield), they are not necessary to be used today as Warner Bros. owns all of the rights to the cartoons. This logo is still found on some public domain prints of various black and white Looney Tunes cartoons.
