It's in the Citadel Mall. It's called Blackstone's or something. Wasn't too much in there. they had some specialty cards, as well as a few books. I haven't been in there recently, so I haven't seen if they've expanded.
Zeezo's downtown is moving to a bigger store. and I actually really like that one. I bought 2 of my 3 Art Of Astonishment books there. They've also got Tarbell, etc... best one in Colorado that I've seen yet.
