"Another Visit for Abbott Labs Director!

John Frederick Richardson, the director for Abbott Labs, a customer of Huntingdon Life Sciences, got another visit about a month ago at his 2732 P street NE, washington DC house. Since our last visit he'd had the door painted a darker color so that red didn't really show as well so we splattered it all over the side of his white house this time.

We're not done yet buddy, quit while you're ahead."
