- let's say original Tintin works were created from 1929 to 1969.
- does this mean only the works released in 1929 are now "remixable"?
- or does it mean that the "concept of Tintin" is now going to be in the public domain?
- (I'm pretty sure the works from 1969 will not be in the public domain).
Steamboat willie is in public domain so that particular cartoon and aesthetic it introduces is fair game but modern day Mickey is not. To simplify: the one with white pants is good but the one with red ones is not.
So let's pretend Tintin had his hair style in 1929 but got his blue sweater at 1969. I would imagine that would mean that you could make anything with a Tintin character (and call it Tintin) that has the hair style but put him in a blue sweater and you'll get in trouble.
It's not just the character name that matters but various other pieces that make up the character and not all of them were introduced or became iconic in the same time period.
Absolute minefield!
