Alfred Higgins Productions
Logo: We see the words fading in:
Behind the name of the logo is a stylized "aH/P" in orange.
Music/Sounds: The synth piano tune.
Availability: Seen on Heritage of Splendor, Foods: Fads and Facts, and other movies.
Legacy: It's reminiscent of Hanna-Barbera's "The H-B Box" logo (even though it predates the HB logo).
