the first i originally saw on my XC ute that i had for a short time, it's in the center of the steering wheel, and is like a diamond with crown on the top. i just presumed the wheel was aftermarket, but i've seen a couple of old x-series falcons in magazines with the same logo.

second is on the side of old GT falcons like were it says '351 GT', it's a kanagroo with big wheel for legs, exhuasts out its a** and an air filter on his back.

dunno about the steering wheel one, but the second is the "superroo" of the XY GT era
