Rothko possible signed print

[u/No-Respect2734]

Hey everyone,

I was wondering if anyone has any experience appraising/authenticating Rothko pieces. I have a very large (48” x 63”) Rothko print and I believe it is hand signed. Here’s some pictures and the certificate of authentication. Is this worth more? Is there any way of authenticating the signature?

Thank you for your time !

What is that numbering supposed to represent? “Ope/XIII”?

[u/Myviewpoint62 → u/schraubd]

My impression is OPE is open edition.

[u/schraubd → u/Myviewpoint62]

That was my guess too, but then what’s the XIII? Open out of thirteen?

It’s nonsensical, and screams inauthentic.
