so...is there any original official link of this pic?

I always hope to find the official link of some pics but it's always a failure.
this should be the very official RWBY art, so those who have been following the RWBY news and are familiar with this topic may have an idea.

EDIT: just found it myself...as predicted, it sits in their official facebook photo album.
