The Rockstar Logo has been featured in every game in the Grand Theft Auto series since the 3D universe debut, Grand Theft Auto III. Rockstar Games has left their logos within the games as Easter eggs. The logos can usually be found on billboards, signs, and even on articles of clothing.
Carl Johnson's suitcase in the first cutscene has the Rockstar logo on it. In addition, OG Loc's, Sweet's and Tenpenny's suitcase (which is the same as CJ's) have the logo on it as well.
Inside Big Smoke's Crack Palace, there is a doormat that says "NOT WELCOME ROCKSTAR NORTH" with the Rockstar North logo at the center.
Many beer bottles in bars and clubs in GTA San Andreas have the Rockstar logo on them.
The Parachute has a small Rockstar North logo on the back.
The action figure boxes for GTA Vice City and Manhunt characters inside Zero RC have Rockstar logos on them. There is also a model sailboat inside of Zero RC which also has a Rockstar logo on it. The kites on the roof inside Zero RC also have the Rockstar logo on them too. A box featuring the logo of GTA Vice City has the Rockstar logo on its side.
The same GTA Vice City texture can be found at the gas station in Dilimore.
