This is a typical Rybra finish around the corner or bottom part of wall.
Rybra Antique Wax has a curious feature. To apply more, the finishing color is getting more dark. And less application causes a lighter color finish.
When imaging the typical antiquating finish, the color is uneven. Usually closer to an edge, a bottom, etc., the color is darker than other parts, that is a typical antique finish.
