Cloisonne (masonry) tile the Porceleyne Bottle of a on sale fantasy ship

This is a masonry tile from the Porceleyne Fles from Delft. These tiles do not have random framing, unlike the decorative tiles. They usually have a brown border. The on sale intention of masonry tiles was that they were bricked in, e.g. in a wall between other tiles.
But this tile is completely cool because it has never been bricked in.
