Invincible Pictures Corporation

Background
Invincible Pictures Corporation was associated with Chesterfield Productions (which distributed all their films). Their directors would be Frank Strayer and Charles E. Roberts. In 1935, Invincible merged with five other Poverty Row studios (Mascot Pictures, Liberty Pictures, Chesterfield Pictures, Monogram Pictures, and Majestic Pictures) to form "Republic Pictures Corporation" (later known as "Republic Entertainment, Inc.").

Logo (1932-1936)
Visuals: On a cloudy background, we see a big rock with an eagle on it, then underneath, we see the words "INVINCIBLE PICTURES CORPORATION" in front of a rectangular rock.

Variant: There is a variant that has a statue of the bald eagle on top of steps on a city background with searchlights. There is the text "AN INVINCIBLE PICTURE" arched above the eagle.

Technique: None. For the variant, it's the searchlights moving.

Audio: The opening theme of the movie.

Availability: Assumed to appear on their movies such as Flaming Signal and Condemned to Live.

Legacy: The use of a bald eagle would later be repeated in the 1947 logo for its successor company, Republic Pictures.
