Following appraisals of jewelry recovered from Imelda Marcos and stored for decades in a vault, the Philippine government has announced the launch of a website to crowd-source tips on the whereabouts of some 200 missing art works, including paintings by Van Gogh, Picasso, and Rembrandt that were owned by the former first lady, reports the AP.

A former aide of Marcos was sentenced in the U.S. in 2013 for selling a Monet waterlily painting for $32 million to a London gallery.

The Monet was part of collection of paintings, jewelry and other allegedly ill-gotten wealth amounting to an estimated $10 billion that have been sought by the Philippines since Ferdinand Marcos was ousted in 1986.

Known the world-over for her outrageous shoe collection amassed during the couple's 20-year rule, Imelda Marcos is now a congresswoman in the Philippines. Her husband died in Hawaii three years after his ousting.
