This is the production company of Jim and Stephanie Graziano.
1st Logo (October 31, 1992-February 21, 1997)
Logo: Against a gray marble background, we see a purple rotating globe. On it is "GRAZ" in a variation on Baskerville, on the middle shape part with two gold eagle-like statues standing on the left and right of the globe respectively. Under it is a dark gold rectangular shape with "ENTERTAINMENT INC." on it, set in Eurostile. All the while, the logo is twinkling.
Technique: The rotating globe and twinkles.
Music/Sounds: The ending theme of the show. G.I. Joe Extreme has a nice piano jingle with strings in the background, ending with a "ding". On that show's first 5 episodes, the logo is silent.
Availability: Can be found on early episodes of X-Men, earlier episodes of Street Fighter, and the first two seasons of The Tick. As far as we know, the version with the jingle only appears on G.I. Joe Extreme.
2nd Logo (March 5-August 27, 1994)
Logo: On a black background, we see a forest green marble plate with "GRAZ" in relief on it. It shines from the top-right to the bottom-left, then "ENTERTAINMENT, INC." wipes in underneath in a white serif font.
Technique: The shining and wiping.
Music/Sounds: The latter half of the 1983 Sunbow Productions theme.
Availability: Was seen only on Conan and the Young Warriors.
