Thus research and analysis show that a large part of the mural was painted over and that the non-original layers of paint and varnish can be removed throughout the mural, admittedly in parts at the cost of many man-hours.

The restoration includes the removal of the non-original coats of paint and varnish and the reintegration of defective areas into their background.
