Can we post other production items?

IE, things that aren't cels or sketches. I wanted to ask before I did to make sure- for instance, I have a script from Hameln no Baiorin Hiki as well as a sketchbook from one of the artists of Hamtaro. If it's not allowed, that's 100% fine, of course- I just wanted to be sure before I potentially broke any rules.

Basically, the emphasis is on production items, including, but not limited to, sketches, cels, scripts, storyboards, etc. So, if the item was used during the production, then it's ok.

We used to have a problem with people displaying their entire gashapon collection, posters, etc. I've been told that as long as the majority of the items displayed in your gallery are 'production art' materials, then having a few posters, figures, etc. is acceptable. I don't know if the rules have changed on that, but most of the galleries you'll find seem to abide by that.

Hope this helps ^_^
