Intermediate status

Intermediate state of restoration, January 2008
Intermediate state of restoration, January 2008

These pictures are supposed to point out the extent of the aesthetical damage caused by the overpaint and the consequence of the restoration treatments:

On the first picture only half of the original paint is exposed.  The old damages become clearly visible in shape of white areas of paint loss on the upper row of panels.  Likewise, the varying degrees of discoloration of the panels are clearly visible. The restoration work, that is the puttying and the retouching, of the second panel from left in the middle row has been completed. To the right and the left of this panel are reproductions on paper – the originals were at that time in the process of being restored. The intermediate state already shows how coloration and spatial effects have changed:  the background is clearly light blue and the green leaves have become more rich in nuances and volumes. It also comes apparent how heavily discolored the overpaint was and how it adulterated the coloration.

On the second picture all overpaint has been taken off, except for the upper left corner. After the removal the change in color is even more apparent. Just as obvious are the heavily abraded areas of the lower panels. These damages are the remains from the time between 1934 and 1960 when the painting was situated  in the Mascotte-bar.
