An iconic image of Marilyn Monroe, created by Andy Warhol, is expected to fetch around $200-million at a Christie’s auction in May.

The silkscreen image, known as “Shot Sage Blue Marilyn,” is a close-up of Monroe with her hair in yellow, her eye shadow blue and her lips ruby, red.

If it meets its pre-sale estimate the 1964 painting would be the most expensive 20th-century artwork to be auctioned ever.

The proceeds will go to a foundation that helps children with health care and educational programs.
