Hot damn! Free Comic Book Day is tomorrow, and Portland's disproportionate number of extraordinarily fantastic comics shops are frantically and enthusiastically girding their loins to make the day a success.

It's a pretty jam-packed day as far as comics go, with signings, give-aways, sales, and more going down at just about every comics shop in Portland—if you can tear yourself away from gazing lovingly at the first official publicity shot from Marvel's upcoming Thor movie (SO DREAMY!), it'll definitely be worth visiting a store or three. Hit the jump for what's happening tomorrow at a few of our favorite nerdery supply stores!

(UPDATE: I just added some sale info for Things from Another World. Keep an eye on this post; if any more info comes in, I'll update it throughout the day.)

(First, a disclaimer: Some of this info is super complete, and some of it isn't—if you have any questions as to what's going on at your friendly neighborhood comics shop, give 'em a call. When available, I've also linked to stores' sites, where you can usually find more info.)
