There are much better (worse!) examples of ridiculously long copyrights.
Take Shaw's play Arms and the Man, written in 1894. In most life +70 countries it only went out of copyright in 2020. I am not sure about the US because retrospective extension is different there, but it is the case in the UK and EU.
