can we post comic art pages?

I don't see a problem myself with that, as long as it is not the majority of your gallery. I have been showing my collection of that type for a time.

Yup, throw all of that stuff in there. Heck, I'll be near the front of the line to check it out. I don't know how to really explain "production art and anything that originated from the creators" in a really concise way, but all of that falls under the kinds of things we like to see here.

As a reminder, we have no bias against non-Japanese animation or comic art. No need to calculate minorities or majorities. If it's original production art, let 'er rip.

I wish there was a single word or phrase we could use to describe all this stuff. Collector's items don't really cut it, because that includes out of print artbooks and phone cards and such. Assuming people know what's acceptable isn't cool either because 1/3 will get it, 1/3 will be nervous that they don't get it, and 1/3 won't have any idea they're doing anything wrong. I like to believe that it's a rare few that get it and flaunt the rules anyway.
