The present lot depicts the IJ in Amsterdam with the Westertoren beyond. J.H.. Koekkoek has excelled in capturing the stormy waters with highly realistic transparent water and exact detailing in the vessels such as the large 'hektjalk'. The artist found many buyers for his works in Amsterdam where he had started exhibiting in 1810. In 1826, seven years after the present lot was painted, he moved to Durgerdam, a small village on the edge of the IJ near Amsterdam. Aside from the skilled execution, the subject of this painting adds to its desirability. A view of the IJ of this monumental size and condition has not been seen in salerooms for many years.
