The Dubya pic does have a URL across the side....hmmmm...folks do that to advertise. Sometimes the cartoons I post change as the author changes them. Odd how it showed up after you posted it tho.
I once posted a Saddam Hussein cartoon where it showed a boot on the wrist of a hand reaching for a ballot. At the top it said "Saddam Hussein Award for Democracy".
A day or two later, I got a FReep mail from Jim Robinson explaining that he regretted he had to pull the image. The clown at the web site was a Liberal, had noticed the excessive traffic on his site, found out where it was posted and sent Jim Rob a nasty note demanding it be removed/deleted. He had also added "for Antonin Scalia" at the bottom, knowing Jim would have to remove it.
Check it out, top right on this page (the thumbnail is without the "Scalia" addition).....
