i have all three of them
DO NOT GET DISCOURAGED BY THE FIRST ONE
i was a bit upset because beyond the recoloring they didn't do much else with what they had. the extras were skimpy, the intro was kind of lame and i was really glad i hadn't spent MSRP to get it.
the second volume, however, is totally fuck awesome reprinting the entire Sandman Month sept 1991 promo stuff including commissioned but unpublished posters, pictures of some of the merch they did like the death watch, the first t-shirt, the making of the first sandman statue (weird inclusion, but neat), it also reprints the ENTIRETY of the pin up book Visions of Dream which were comic artist interpretations of Dream and co and finally contains the script and roughs for chapter 2 of Seasons of the Mists.
volume three raises the ante even more
collects the never collected predecessors to the pin up comics, promo Endless art, more merch (endless pewter figures? ren fest exclusives or something?), the cain and able book ends and the concept sketches for them, the follow up to Visions of Dream the Endless Gallery (another collection of pin ups), an entire section on The Little Endless by Jill Thompson, the script notes and roughs of issue 50; Ramadan, and P Craig Russel's statuary design and it reprints the end notes from the original trades.
I can't wait to see what's in store for the fourth and final volume of Absolute Sandman
