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。

Allegory of Painting:
This uncradled oak panel has bowed. There is a partially visible horizon line of discoloured retouching associated to a split through the middle of the panel. 
Examination under ultraviolet light confirms the aforementioned retouching and scattered spots of minor retouchings elsewhere.
