What is the Met's Most Expensive Work of Art?

And the answer is ...

c) Duccio's "Madonna and Child"

Sometimes known as the Met's "Mona Lisa," "Madonna and Child" was medieval master Duccio's last known work in a private collection before it was sold to the museum. Although the sum paid for the painting is confidential, it is known to be the priciest purchase for the Met ever; sources say the museum paid over $45 million. You can see this famed painting, from the 1300s, on permanent collection in the medieval painting gallery!
