The girl who gave that to me said it was the deluxe edition but I suppose that this term would be better used for the Millenium edition in 7 volumes.
What this former student gave me is THE LORD OF THE RINGS, 1992 (Centenary Edition), Harper Collins, illustrated by Alan Lee (50 plates), 1195 pp. in three paperback volumes. As for the quality of the plates, the picture of Frodo looking in the mirror of Lady Galadriel at the homepage of the site I mentioned in this thread is one of them. They are 7.5"x5" glossies.
Galadriel
Here are the 
50 plates and here's where you can 
download them.
Here's more info I found on these 50 plates:
 
"To all Tolkien fans:
A request was made and most likely has been made a number of times regarding the titles of the 50 color plates painted by Alan Lee and commissioned by Harper Collins in the single volume hardcover LOTR 1991 ISBN 0-261-10230-3. I believe that this volume came out also as the three books: FotR, TTT & RotK with the Alan Lee watercolors in them to. They have been scanned and are available still on some FTP sites, and are listed as Lee01.jpg to Lee50.jpg. Unfortunately these names are somewhat cryptic and require that every file be uploaded before anybody can see what they actually pertain to.
As a favour to a friend, and to all the contributers of my two favourite news groups on Internet - the Tolkien news groups in the rec. and alt. heirarchies here is a list (as accurate as I can make it) of the Lee01-50 pictures. There are no titles as such they were excluded when going to press, but Alan's art is of such a high standard that with a little effort the names can be guessed.
A large number of the illustrations were titled by Alan but these were got from another publication from Harper Collins "Tolkien's World" 1992 ISBN 0 261 10276 1. I cross reference them with my own guesses.
