Anime-Beta TNG

i wasnt quite sure where to put this but i bought some thing with this descrption 秘原画集.
i was wondering if anyone knew what this meant in relation to gengas?
thank you in advance. glad to see the site back though ive mostly been a lurker lately.

The translator site I use translates it to "use only original illustrations"

In plain kanji it would be something like never-before-seen/unraveled genga assortment/collection...but I'm no kanji expert so don't quote me.

I believe sometimes the 秘 kanji can be used to censor things or could have some relation to adult material? Otherwise, it basically means "secret" or "confidential".

Of course, 原画 is "genga" with 集 referring to a "collection".

Does that help at all? I'm not the most knowledgeable when it comes to the paper side of the hobby. xD

Thanks guys/gals. I don't have the item with me yet. I probably should just have SMJ ship it. My main concern was whether these were original materials or a copy (similar to settei). It would be nice if it was "never seen before" though "secret" was my initial translation too, it's not adult material so I think that's out. So it's not a commonly used term I guess in paper collections. I'll let you know or describe it once I get them!
