Gunther-Wahl Productions, Inc.

Background
Gunther Wahl Productions was an animation company formed by Lee Gunther and Michael Wahl.

(1992-August 27, 2006)
Logo: Over a brown stone background with cracks in it, an animated blue sleeved hand plants a stamp on the background. With his other hand, he taps the stamp with a mallet and he pulls both the hammer and stamp away, revealing an emblem with a conjoined "GW" in it, surrounded by "GUNTHER-WAHL" on top, and "PRODUCTIONS, INC.". The whole emblem is slightly slanted.

Variants:
 * A still version also exists (which is far more common).
 * On some episodes of The Adventures of T-Rex, the man hits his thumb with the mallet and says "Ow!" as his thumb turns red from hitting it. He shakes his hand in pain as he pulls both the stamp and the mallet away as well.

Technique: Digital ink and paint. Otherwise, none.

Music/Sounds: A descending dramatic theme, followed by some xylophone notes and some drum beats, concluding with a peaceful piano note. The man saying "Ow!" for the variant. The still version had the closing theme of the program.

Availability: The animated version is very rare, and it was only seen on The Adventures of T-Rex. The still version is easier to find, and it can be seen on The Angry Beavers and the obscure animated miniseries Red Planet.
