Can't go wrong with some virgil finlay art...
hmmm... top one reminds me of that old jeff grosso demon graphic. or other way around???
ask jim phillips.
or ask VCJ. look at the tony hawk bird claw graphic background and then this piece.
art by theodor kittelson.
even the skeleton in this one is similar to the kittelson forest road pic above...
original artwork for the grosso toybox - jim phillips
last but not least some misfits by pushead.
