«Acanthes» is in a good state of preservation. There are no serious damages or changes within the image area. However, previous transports and loans have had a detrimental effect to the edges. During these procedures the work was removed from and restretched tot he stretcher several times, a measure that was common until the early 1970s for works of this size. This resulted in cracking, creases, and partial delamination of areas in the paper support. The adhesive employed to repair these damages in the past has discolored.
Currently, initial conservation measures are being undertaken. For this purpose, «Acanthes» has been laid flat on a large worktable in the studio, visible to museum visitors. On the one hand, the paper along the damaged edges is re-adhered and traces of visually disturbing discolored adhesive will be reduced. Simultaneously, the canvas, weakened by repeated de- and restretching, is being stabilized. Finally, small retouches will be undertaken locally along the areas of the edges.
