Muckle Man Productions

Background
This is the vanity plate of Roberto Aguirre-Sacasa.

Logo (September 9, 2010-)
Visuals: On a white background, we see a stylised typewriter with octopus tentacle-like things typing on it, holding a pencil in one arm and a pair of glasses in another. The text "Courier" is seen on the paper, as the tentacles then type in "Courier" on the keys. Below it is "PRODUCTIONS" in a stylised black font with lines surrounding it inside a yellow border.

Trivia: This logo was designed by artist Phineas X. Jones, and posted on his Flickr account in 2010.

Variant: There exists a scope version.

Technique: 2D animation.

Audio: The typewriter typing, followed by a ding. During this, the sounds of the tentacles can be heard.

Availability: Seen on Chilling Adventures of Sabrina, starting with season 2. Also seen on Pretty Little Liars: Original Sin.
