the end of the run was announced later and tanked the book. the 9.9 auction sub-title says it all. "the next walking dead?" is what people are chasing with all these Image books.
If and when that gets taken off the table for any of them, implosion occurs. ToT is the "next walking dead", if there is one.
Revival is a good story, and its variants or ultra high CGCs will sell well. The main books are stalled hard, due to huge print run, and over abundance on ebay.
Huge print run? If everyone in my small town got one, there would be none left for the rest of the world.
