From the Introduction:
Extracted from the Original Campaign notes and fully detailed herein are some very potent magic items... Their descriptions in many cases reveal tales of their origins and, in turn, other matter that existed or was being developed for the Original Campaign by myself 1973-1983.
A list of 25 magic items along the lines of those in El Raja Key's Arcane Treasury. This is a set of 15 loose pages plus a heavier-stock front cover in a plastic bag. The last two pages are scans of Kuntz's original handwritten notes.
