Japanese print(s)

Dear all, I have two japanese prints (i believe woodblock prints) that has been framed badly and now stained from bad acid from previous framing. Living in Norway, framing is very expensive (and quality, i must say, very bad) - and my question is if anyone knows about this printmaker, and can tell me if it is worth saving? I only have photo of one of them, but it is a pair- both in similar condition. Anyone who can give me an advic e here?
