Looks like the Lexus logo in the corner of an iPad (on top of another iPad.)
Christ, that logo looks like it walked here from 1990
Gotta admit, I prefer the one they're currently using.
No,that logo was never used.
Even ZeniMax,s website back from 2000 had the same logo they use today.

That logo looks more like it ran away from an industrial rock band to me. Maybe some Nine Inch Nails side project. It kind of looks cool in that context.
