I thought I would start with one of my most recent acquisitions. This book is a postcard book produced by Matt Groening in 1990 (right at the height of the Simpsons' licensing craze). This example features a sketch by Groening on the inside back cover.
Author: Matt Groening
Edition: 1990-11 First Edition with # line starting with 2 (probably a 2nd Printing but I'm not sure with this publisher).
Each page of the book is a different character postcard (that can be removed and posted). What makes the book interesting is the Matt Groening sketch on the back cover, inscribed "To Mike!!! Your Pal, Matt Groening 12-18-1990" which was fairly close to the date of publication.
