Question about translating and adapting comics

[account_disabled]

Hello!


I have one question:

I was looking at these items: "public domain Golden Age Comics"

I am able to translate and adapt some of those series to Portuguese language of Brazil: All love, Western Adventures, Apache. AND CONVERT THEM TO KINDLE FORMAT

I use Gimp, and I have comic life3

But my question is:

Is this allowed?

Or where to get the license for it?

Please help...

I didn't find the right solution from the Internet.
