By the way, Disney's first production of a Winnie the Pooh cartoon dates to 1963. Of course in the 80s and 90s there was new productions of TV shows, etc.

Don't know too much about the despute, but I know I have several rubber stamps with "classic" Pooh (i.e. pre-Disney images) scenes and characters, all of which are clearly marked: Copyright Disney. There date from the late 1800s to the late 1990s.
