Yea man! I have all the HCs here, quite a fan of the series in fact, especially as of the last few volumes. I forget to mention it sometimes because it stands outside the Mignola-verse as it's own thing, but that's one of it's biggest strengths, someone wants a Mignola thing but doesn't want to go balls deep on Hellboy/BPRD/so on, you've got Baltimore right there. The scripter on it is Chris Golden ,who was actually the scripter on the original BPRD Hollow Earth story that kicked everything off with the BPRD books, and he does some great work. I wrote a little back in August actually. It was about Chapel Of Bones, which is vol. 4, but I specifically made sure not to have any spoilers since I was trying to sell the series haha

It's very cool, and a nice twist on vampires, just the way they're picked the setting and period, it opens up some really fun storytelling. I'm guessing you'll go digital, but the HCs are actually REALLY nice too, I love them.
EDIT: OH and if you see Joe Golem while you're looking around, that is Mig & Golden's other thing they do together. They just kicked off the comic series and that is also it's own totally separate thing to HB & to Baltimore.
