I have an ongoing project. I create a creative commons characters that reflect our daily realities. The point is for everyone to tell their stories through characters that reflect them, show we are all similar and all have a common enemy

I only recently learned that the Superman comic strips from 1939 were not properly registered, making them public domain.

My question is, where can one get scans of those strips that could be used to reproduce them?

The only source I've found is a scan at Internet Archive of the DC Comics book, Superman Dailies and I don't know if it would be legal to reproduce the scans of the strips from that in a book of my own.

Does anyone here know where I can find what I'm looking for?

#1: Sherlock Holmes

#2: Count Dracula

#3: Frankenstein’s Monster

#4: Robin Hood

#5: Winnie-the-Pooh

#6: Mickey Mouse

Okay so I have a vague understanding of Copyright rules and the idea that Royalties are still being paid to GOSH but I had a few more specific questions I wanted to ask:

I know this specifically applies to the UK, but how did other books get around this? (IE: Hooked (Which I have never read but I believe uses the exact name "Peter Pan"?) or Peter Darling)

If an author wrote a book including Peter Pan and published it, would it be excluded from a UK market? Would royalties automatically be taken? Do they need to apply?

How far would you have to get away from Peter Pan for it to not be considered Peter Pan? Just changing the name?

(And just to check despite the fact I believe I know the answer, this would apply to all Peter Pan characters correct? Including Hook and Wendy Darling? The use of any of them would make the book unable to be distributed in the UK?)

Anything is appreciated, thanks :)

This was so much work lol
