The following condition report is provided by Hamish Dewar who is an external specialist and not an employee of Sotheby's:

Structural Condition

The artist's very fine weave canvas has been lined onto a secondary canvas and this is ensuring a sound and stable structural support and the canvas is securely attached to what I assume is the original keyed wooden stretcher. There is some staining on the reverse of the canvas. The overall structural condition would appear to be very good.

Paint surface

The paint surface has an even varnish layer and only very small retouchings, predominately along the lower horizontal framing edge, are visible under ultraviolet light. There are other very small spots of inpainting.

Summary

The painting would therefore appear to be in very good and stable condition and no further work is required.
