I am looking for a book I had in the 80's. It was a colored illustrated collection I believe of Ray Bradbury stories. I remember it had The Veldt and a robot story with the laws of robotics. Can anyone help?
No, I don't think that would be the case. The Illustrated Man was the third of Bradbury's books, a story-collection-cum-novel; yes, "The Veldt" is a story included (it is, in fact, the first following the framing story), but this is not an illustrated book, which is what the OP is looking for.
I know I've seen something such as what you describe, but I don't recall anything dealing with Asimov's three laws... in fact, as far as I recall, Bradbury never paid attention to such in his own work. Could this perhaps have been an illustrated anthology of stories by various writers rather than a single-author collection?
