Can anyone find the far side cartoon where the alien is flying his space ship and it has a bumper sticker that says "Ray guns don't kill Zorbonians, Zorbonians kill Zorbonians."

Is it possible that an image is not on the internet?  I've done image searches every way I can think of.

I have all the Far Side galleries and have looked through them repeatedly.  

I found numerous references to this cartoon on the net but no image of it.

So I'm callin' in the A-team (the A stands for ARFcom).

Are you sure it wasn't a photoshop (or copier art from the Far Side timeframe) and maybe not an original Far Side?

Edit:  I do see the other references to it, but it's all people remembering it or looking for it.  I suspect mass psychosis...

I saw it many times over the decades, didn't put a bookmark in my books, and I still think it's in my gallery books although I can't find it.  

Lots of far sides on the net, just not this one.  Somebody's got to know which book it's in.

The alien driving the space ship is dressed like a redneck.
