I read a short blurb inside the issue (can't remember exactly where) about the person responsible for producing the holograph and how it was done. Look inside the front cover or on the contents page for a paragraph that descirbes the cover. I believe it references the blurb that is elsewhere in the issue. And you're right. The effect is startling. Dennis R. Vogel AT&T Information Systems S. Plainfield, NJ
