The falls on the Rhine at Schaffhausen

After a short period in Paris, Bleuler returned to his native Switzerland and established his studio in the Castle of Laufen, situated on the left bank of the Rhine above the falls at Schaffhausen. Below the castle wooden scaffolding provided a platform from which to view the falls, a popular destination for tourists and artists since the late 18th Century.
A similar drawing by the artist of the falls at Schaffhausen was sold Christie's London, 4 July 2006, lot 135.
