Kurt Cobain Autograph 'Kurdt' : Real?

[sergio712]

Hello. I am new here so if there is anything I am doing wrong, please tell me.
I have found this in my father's autograph's album.

I have put it to sell on Ebay and I would like to have any kind of confirmation from people that have knowledge on these things.
Do you find it real?
It says 'Kurdt', but I have already seen some of them which are signed this way.
Thanks!

I forgot to comment that it is a piece of paper from a vinyl disc covering.
