Summary
Cover art from The Glittering Plain, by William Morris, Newcastle Publishing Company, 1973

Rationale
Fair use claimed for image:
 * illustrates the subject of the articles The Glittering Plain (on the book itself) and Newcastle Forgotten Fantasy Library (on the prominent reprint series it was issued in, it being the first book in the series).
 * no free alternative.
 * the size and resolution make reproduction for bootleg copies difficult.
 * reproduction does not detract from the commercial value.
