Reasons for the restoration

The main reason for the restoration was conservation issues. Remarks concerning ‘inadequate adhesion’, ‘layer separation’ and ‘flaking paintwork’ can be found in descriptions of its condition almost contemporaneous with its first recording in the Kunsthaus files in 1965.

These adhesion problems had resulted in numerous small areas of paint loss. Parts of the paint layer were also lifting, and were in danger of coming loose and falling off if the canvas was subjected to shocks or vibration, for example during transport.

The focus of the restoration work was therefore on preserving the substance of the painting and preventing further damage. It was to be accompanied by a systematic check of the paintwork under the microscope.
