Dutch school (ca. 1800). 'View of a river w. a dilapidated building and a fortified Dutch town

in the background'. Grisaille drawing, 15 x 25.5 cm, signed "H.J. Gans" (?) in pen in lower left corner, framed under passepartout.

The back of the frame w. mounted attribution to Gerhardus du Pon, in our opinion incorrect.
