Could say that about a lot of the classics - Rembrandt, Rubens, Titian, Van Dyke. There's a lot of fakes out there! But no-one wants to spoil the party....
As I understand, the notorious fake Vermeers all try to imitate his early style, vaguely Baroque (?) rather than the later camera obscura-assisted works. I love 'em all but so does everyone else so this show will probably be super crowded. He did have one really hot model and one not so hot, which has always puzzled me. Then again apparently he was a bit of a dipso, so he just might not have noticed.
I also love Terborch (or ter Borch)
