Large Woodcut Abstract - Trying to identify artist

This looks like a woodcut to me, on paper - about 56 X 72 cm.

Signature in pencil on lower right looks like "Max 00". Lower left has P.A in pencil - I think that is "Artists Proof" in Spanish or Italian.

There is a partial paper watermark - I've included a photo of that. I think it is "Guarro", a Spanish papermaker. I've included a sample of that watermark I found on the internet for comparison.

Any help on identifying the artist is appreciated.

 

According to this, Guarro paper is made by CANSON, a French company.

Ah, but there's a paper making company called GUARRO CASAS in Spain.

Yes Debora, I think it was GUARRO CASAS that I assumed was the paper maker.

 

Got it.
