RKO Radio Pictures/Logo Variations

Snow White and the Seven Dwarfs (1937): Neither the "Transmitter" nor the "Thunderbolt" logos are shown before the film, only a text notice shown after the title among other credits. The "Thunderbolt" closing logo still appears at the end, but on a jeweled background, with the words "A WALT DISNEY FEATURE" in white, "Production" in bright turquoise script below that, and "IN TECHNICOLOR" in white below that in a smaller face.

Pinocchio (1940): The "Thunderbolt" logo is carved into a wood background.

Fantasia (1940, 1941 re-release): The "Thunderbolt" logo is seen at the bottom of the film's intermission title card.

Dumbo (1941): The "Thunderbolt" logo is in gold on a blue background within a stylish gold border; all of this is on a red background.

Bambi (1942): The "Thunderbolt" logo is in dark teal on a lighter teal background, and there are branches with leaves (in the same dark teal color) surrounding the logo.
