Copy after lost Bosch original

At Leclere via Drouot, they sell on 18 April 2015 a correctly described copy after Hieronymus Bosch, "Crown of Thorns", estimated at 6,000 to 8,000 Euro and dated to about 1600.

It is one of a few paintings which are commonly accepted to have an original by Bosch, even though no original is known. The best copies are kept in the Museum of Berne (as said by Drouot, and depicted in black and white above) and in London, with another very similar (but with a donor added) early (1520-1530) copy in the Museum of Antwerp (second black and white image above). The one for sale, while later and lesser quality than the three I mentioned, is still a good and relatively affordable way to have a real old Bosch copy, which isn't that common anymore on the market. The chance that you are buying the original Bosch seems extremely unlikely though.

The above are other copies from the Msuée Magnin in Dijon and the Philadelphia Museum of Art.

The most unusual variation I found was the above, from a private collection in Sint-Niklaas, Belgium.
