That IDW Humble Bundle is simply fantastic. Maxx as has been said is astonishing. I'm guessing it won't be to all tastes but if it clicks with you, as it did with me (and Hawkmumbler) you in for a very rare, very rare treat indeed. Not like anything else out there.
Also enjoy Winter World, fun action comics, Little Nemo is a little gem and not surprised to see Link Prime recommend the simply wonderful Ragnarok. I've got Lock and Key and the Parker books (well its the late GREAT Darwyn Cooke so they gonna be good) lined up for reading soon from some deal other.
So yeah I won't be going for this but if you don't have those I've mentioned this is a FANTASTIC deal.
