Travis: I can't speak to authenticity, game use etc. Sigs are really faint and won't help matters. Attached are a photo I bought from Robert Klevens with Oana's signature which I believe to be bona fide plus a jpeg I copied from an eBay sale which purported to be his autograph. I will make a semi-educated stab that the sig at top in your fourth photo is meant to be Oana's. Whether it is real or not is not for me to say.
