These are four paintings by Pieter Bruegel the elder. They all use justmoi's "Majestic" Glamour mesh. You need the
New Mesh "Majestic Glamour" Painting to have these paintings appear in your game.
They require the Base Game and at least one other Expansion Pack for the paintings to appear in your game.
