1st Logo (1945-1955)
Logo: This is not really a logo, only an in-credit disclaimer. At the start of the film, it says:
BARTLETT TOY STUDIOS
But at the end of the film, it would just say:
PRODUCED BY BARTLETT
FX/SFX: None, this is a still logo.
Music/Sounds: None, or the film's opening/closing theme.
Availability: Very rare, this was seen on films from 1945 until 1955.
Scare Factor: None, it's just plain boring.
2nd Logo (1955-1966)
Logo: On a red background, we see the words "Bartlett Toy Studios" in white.
FX/SFX: Again, none.
Availability: Seen on some Bartlett Toy releases during the time.
Scare Factor: None, it's plain boring anyway.
3rd Logo (1966-1985)
Logo: On a black background, we see red stars around the screen and the words "Bartlett Toy".
FX/SFX: Once again, none.
Availability: Seen on Bartlett Toy releases from 1966 until 1985.
Scare Factor: None, once again.
4th Logo (1985-2007)
Nicknames: "Mario!", "Star Mario", "1st Appearance of mario"
Logo: On a red background, we see Mario, with his left hand up. On the top, there is a star. Suddenly, he shoots the star, revealing "Bartlett Toy Films" in blue with a black outline.
Music/Sounds: A "WHOOSH!" when Mario shoots the star, then none.
Availability: Seen on every Bartlett Toy Films release until 2007.
Scare Factor: Medium, that loud "WHOOSH!" will scare some off.
5th Logo (2007-)
Nicknames: "No Mario", "Still Bartlett Toy"
Logo: On a blue light background, we see "Bartlett Toy Films".
FX/SFX/Cheesy Factor: What happened here? Besides, the logo makes NO sense and Mario isn't even in the logo! C'mon!
Music/Sounds: A short fanfare.
Availability: Rare. Can be occasionally seen on Bartlett Toy releases from 2007.
Scare Factor: None, you'll just get annoyed by the lack of mario.
