Your last chance to collect a Vermeer

Are you in the market for a Vermeer? Act now. You may never have another shot.

This evening in London, Sotheby’s Holdings Inc will offer for sale the delicate “Young Woman Seated at the Virginals” from about 1670.

The painting, being sold by the heirs of the Belgian collector Frederic Rolin, measures just 10 inches by 8 inches. Apart from the majestic “Music Lesson,” which belongs to Britain’s Queen Elizabeth II, this is the last of the 35 generally accepted Vermeers in private hands.
