It immediately caught my eye as it has all the characteristics of a good Early Netherlandish painting from the early 16th century, and looks way too good to be a 19th century copy / fake / pastiche.
Christie's, (sold for an excessive £26,000) to much more similar ones like this "follower of" at Koller (sold for 12,000 Swiss Francs).
Comparing the work for sale with other Massys works, and the copies we found, I got convinced that this was an original ca. 1500 work, either the actual (lost) original by Massys, or a very good workshop copy. My contact pointed out one major problem though; all known Massys works are on panel, and this one was on canvas.
RKD, a copy for sale at Charlton Hall Galleries in 1950: it had nearly the exact same composition right down to the details, but the execution was less precise, less convincing, especially in the face of the virgin (work for sale added below it for easy comparison).
I loved the painting, but didn't dare to believe that it was the actual original. Perhaps the hands of the virgin weren't executed with enough skill? But it seems that at least a few buyers went all the way as it sold for 110,000 Euro. Which would be escessive for a relined good copy, but for an actual original, even with these problems, would be a good buy, whether it is for a collector, a museum, or someone hoping to make a profit by bringing it to a major auction house with a better description.
