Interior of the Nieuwe Kerk, Delft, with a trompe l'oeil curtain

The condition of lots can vary widely and the nature of the lots sold means that they are unlikely to be in a perfect condition. Lots are sold in the condition they are in at the time of sale.

The canvas is supported with a glue lining and the paint is stable on the support. There is a 5 inch vertical scratch at the lower left edge, and a 1 inch horizontal scratch with two corresponding losses nearby. Another small loss is seen at the upper right corner. Under natural light, a craquelure is seen in places. Discolored, greyish-white retouches are seen here and there across the painting. These appear to have been clumsily applied, and the extent of the damage beneath them is unclear. Under ultraviolet light, passages fluoresce faintly on the curtain, on the clock, and in places over the figures in the foreground. It appears that the painting has not been conserved in many years, and a sensitive cleaning should improve its appearance.
