Yep, that little girl/puppy picture (also the foot-on-the-snake picture) have been indelibly imprinted on my mind.
Not too long ago at a medical round table I was approached by two mental health specialists and each recounted middle-age JW patients who brought up those very images. These providers said the patients were haunted by the illustrations, in particular the one with the little girl and puppy being killed at Armageddon. It is beyond paradoxical to tell a child God loves you, but even as a child God will kill you and your puppy (and throw your doll in an abyss!) because your parents aren't living right. It is mental abuse. That's what it is!
