Copies of the Swords & Wizardry Core Rules are now for sale on lulu.com!
It's even possible (but right on the edge) that someone ordering today would get the softcover in time for NTRPGCon. I think the hardbacks take longer for lulu to make (and would delay delivery of a softcover if in the same order). So I think I missed that deadline by a whisker, although it's possible it might still work.
My only real fear with these things was that the words on the spine would ... miss the spine. I'm not the best graphic designer in the world. But it worked, and the words are in the right place. Sweet.
