Between pages 32 and 33 of this issue of Advance Comics, there's pages TB-1 - TB-32, referred to as the first issue of True Believer. This is just promotional material from Marvel, with a foreword by Stan Lee.
Pages 147 - 151 form Ultrawatch, a fictional in-universe newspaper. It has a cover page, 2 pages forming an article, a little over a page with "The Year in Review" (a similar article), and "Why I Hate Ultrahumans" (an editorial by Al Baker).
Notes:
These pages include a "Walter Simonson's Top Ten List" of his favorite series, and some sketches with commentary. On some of these sketches, Simonson is talked about in the third person, suggesting somebody else wrote at least those.
