This is the logo of executive producers Peter Maris and Mark H. Tuttle.
(1989-December 8, 1993?)
Logo: On a black background, in a stop-motion-like style, while flashing colors and moving from the bottom of the screen, a box, with parts of it connecting ala Karl Home Video, pans and zooms back. The box also has the letters "PMT" in a fancy font in it as well. The box flashes, and "PMT" turns into a black-blue-purple-orange gradient color. The box's parts also turn black.
Variant: A short version, starting with the flash, may be used instead.
FX/SFX: The zoom out, the flash.
Music/Sounds: A piano flourish, followed by a synth theme and a "BONG!", finally ending with 2 synth piano notes.
Availability: Appears on the English dub of the anime The Swiss Family Robinson: Flone of the Mysterious Island. It could possibly be seen on First Flights with Neil Armstrong.
