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.
The copper plate makers mark was in use from the late 1560's until the 1640's. We are grateful to Jørgen Wadum for his help in identifying the copper plate makers mark.
