Title: THE ILLUSTRATED HITCH HIKER'S GUIDE TO THE GALAXY
Author: Douglas Adams
Publisher: Weindenfeld and Nicolson
Format: HB 96pp
Pub Date: 22/09/94
The ultimate title for Hitch-Hiker fans. The book is crammed with gimmicks
such as voice chips, double gatefolds, 3D effects and the sort of tricksy
visual puns that one would expect. The book is illustrated throughout with
graphics created using the latest state-of-the-art technology and is
packaged in a shiny silver and "starfield" jacket that is so stunning that
we couldn't possibly reproduce it.
Now for the commentary:
It doesn't have voice chips OR 3D effects. What it does have is an
annoying puzzle created for the book and credited on the opposite of the
title page to DNA, and no one knows what in blue blazes it is!
Also, The reviews on this little item have been less than glowing. My
opinion is it stands as a fine gift for the collector that must have every
DNA item in existence. You should be able to find it discounted for around
US21.00 at many US chain bookstores...
