You made a very good selection, @Kouba01. In fact some, even if they are not on the list, should be. As for example La chica del arete de perla also considered as the Dutch Mona Lisa. I also have my favorites that aren't among the most famous, but I thought they might be. This is the case, for example, of El Bosco's Garden of Delights. That is an impressive painting with a very rich meaning. I always appreciate your comment. Greetings
