Lined, three keys missing, a little slack. A quantity of dirt and debris behind bottom stretcher. There is a noticable line around the edges of dirt and disrupted varnish, likely where it was in a slightly smaller frame. Brittle age craquelure throughout, mostly stable but with a little elevation and a few sharp lifting points associated with blows from the reverse and at the bottom edge. There has been a history of flaking at the bottom edge and at the left edge, which appears mostly stable at the moment. There are however, small areas of associated loss of paint and ground, with some crude retouching to these in places. There are scattered losses throughout, some partly retouched and some retouched (it appears that the retouching might have been partly removed??). See images. Some of the losses are unretouched. The larger losses are located at the bottom edge, to tle left of the jewelled crown, to the bottom of the lace where it falls over the bust etc. There are scattered losses, retouched, in the face including in the forehead and eye. It is difficult to see any further losses in the background due to the degraded old varnish. There has been a bit of abrasion to the paint layers. There is a thick degraded varnish, yellowed, with an uneven surface gloss, minor scuffs, surface dirt, drips.
