拍品的狀況可能存在極大差異，而由於其性質使然，拍品難以處於完美無瑕的狀態。拍品均以拍賣時的狀況出售。

The painting has been executed on a copper plate, which remains stable and shows no signs of warping.
Examination in natural light shows some thinning to the upper paint glazes, notably in the still life details. There has been some loss of the gilt paint to the trompe l'oeil frame. The painting has been selectively cleaned, for instance over the dragon in the background at centre right. The original signature at upper left has been painted over and the van Mieris signature added at lower left. There is evidence of some scattered retouching.
Examination under UV light confirms these observations.
The details of the central figure can still be well appreciated.
