If I didn’t already own it, I’d get this nice edition from Hi-Fructose.
Edit: Oh, never mind. This one is also by Fantagraphics. I wonder if they are going to reprint the whole series in this larger format.
Edit 2: I see. They did it to match that combined volume of the other three books plus a new one which, to my annoyance, is the only way to get the final book in the series because it’s not printed separately.
