Mona Lisa is, alas, a terrible example. It’s a (small) painting famous for its very finely blended brush strokes, and yet it’s behind two layers of protective glass, a barrier about five metres away, and there’s generally about ten thousand tourists queuing up to see it. It’s something you go to have seen, rather than to see.

Unless you wanted an example of a retro game that you play to have said you’ve played it, not too actually play, in which case it’s a superb example. Plenty of games that were legendary at the time but who’s gameplay doesn’t hold up any more.

The Louvre has some massive rooms full of Raphael masterpieces and Gericault’s “Raft of the Medusa” just down from the Lisa - those are well worth seeing in the flesh, big pictures that reproduction doesn’t do justice to.
