I can't speak to the intent of the other post, but, while a key book, the print run on Rai #0 was large (well over 100K) for a non-big 2 book, as the heavy Valiant speculation was underway when the book was published. There are plenty of copies out there, although many may not be readily available.
That is because someone pointed out a Glossy/Not as Glossy variation in the print run. Everyone is scrambling to see if they get an early glossy to try and cut down on the print run number being so big.
The only issues I see, is that many of these books will be banged up from the Valiant crash dollar box syndrome that plagued many of these Valiant books. Original numbers were high, how many are left intact?
I have 0 slabs, and I am scared to admit my first may be a Harbinger #1 or a Solar #3.
