Human Woman, Inc.

Background

Logo (June 24, 2022)
Visuals: On a grainy white background with a thin black border, there is the drawn sketchy text "Serif". It then fills with color, and the rest of the logo appears, revealing it to be on a gravestone with several flowers surrounding it.

Trivia: The "b 1982" part of the logo is a reference to the birthyear of Jenny Slate herself.

Variant: A still in-credit version is seen at the end of the film alongside other logos.

Technique: Computer animation.

Audio: None.

Availability: Only seen on Marcel the Shell with Shoes On.
