Sandman is one of those books I feel bad about for not reading more of. Back in the mid-90s, DC began publishing (along with black and white versions of Alan Moore’s Swamp Thing) Sandman under the header Vertigo Essentials. I bought ’em all for the 20 issues it lasted, and I enjoyed it greatly. Then I forgot to ever go back and buy the trades or back issues.
Then a few years back DC began publishing the Absolute Editions, which were gigantic, hardbound, slipcased editions. The only one I ever bought was Sandman Vol. 1, which had those same 20 issues (which I had subsequently gotten rid of in the intervening decade) but recolored and gi-normous. And I loved it again, but forgot to buy the remaining volumes (though at 99 bucks a pop, you can see where the strain on my wallet might be).
What I’m saying is that I will gladly accept volumes 2-4 of The Absolute Sandman as gifts.
