I collect comic books as well. Here are the methods that comic collectors use to remove musty odor and smoke with good success:
1 - fill the bottom of an air tight container with baking soda. Place the item in the container suspended above the baking soda. You can use a cookie cooling tray or something similar to suspend the item. Seal the whole thing up and let it sit for a few weeks. Repeat process with fresh baking soda if necessary. (I have heard that people have used kitty litter with success as well.)
2 - Place the item between two sheets of microchamber interleaving paper and seal it up in a bag. (Microchamber paper:

Let it sit for a few weeks and repeat if necessary. It will definately work.
Microchamber paper is expensive and usually only available in bulk. I'd be happy to send you a few sheets if you want to PM me your address.
good luck - Steve
