Alguém poderia me ajudar a descobrir que fonte é essa?
Could anyone help me figure out what font is this?

Goudy Catalogue  Suggeriti da Heron2001 

It looks like an 8th generation xerox - of Goudy.

Thanks, just the letter "K" which is a little different, but have helped me a lot ^^

Actually, all of the letters are different. While it's clearly based on Goudy, it isn't the version suggested by Heron2001.

Do you have any source of suggestion that is more identical to what I'm looking for?

Must it be this eroded?

I would be happy if the same font. But it may possible to be more identical

It is the Times Roman/Times New Roman, you have that one. I can't find this eroded variation.
