Christie's charges a Buyer's premium calculated at 23.205% of the hammer price for each lot with a value up to €110,000. If the hammer price of a lot exceeds €110,000 then the premium for the lot is calculated at 23.205% of the first €110,000 plus 11.9% of any amount in excess of €110,000. Buyer's Premium is calculated on this basis for each lot individually.
Dr. Wolfgang Schulz will include this drawing as no. 539a in the forthcoming second edition of his catalogue raisonné of the drawings of Herman Saftleven.
Dr. Schulz has kindly pointed out that the composition of the present lot was also used by Saftleven in a drawing now in the Koninklijk Huisarchief, The Hague (Schulz 409). The drawing cited in our catalogue entry (Schulz 358), of which there is also another version in The Hague (Schulz 410), shows the Bijlhouwertoren from the opposite direction to the present drawing.
