You judge. Here are some scholarly takes, pro and con, along with more photos. It doesn’t look right to me, but many art experts now say yes. About three million pounds is at stake, according to The Telegraph. Since there are only about 35 other Vermeers in existence, and the last one was sold eighty years ago, I suspect it will go for more, no matter what the doubts.
My take: Researchers spent about ten years studying the picture. If it takes so long to tell the difference, spend your money elsewhere.
