HI Nuno,
Just sent you an email before I saw this post.
Sorry about the non-PD scans. I've got some bad news for you.
Checking
Forbidden Worlds it only went 84 issues and all have been scanned.
But there are no rules against a second scan of the same book on DCM.
We don't share ANY comics published after Dec, 1959.
So we cut off Space Adventures with #31.We also cut off Adventures into the Unknown with #112.
I checked
CB+ where they WILL share post 1959 comics in some cases.
Space Adventures #54 has already been scanned.
http://comicbookplus.com/?dlid=12684Adventures into the Unknown they say is only public domain until #146 so best not scan that either.
I'm glad you posted this list. I hope this saved you some time.
Take care,
-Yoc
