Margrethe II

A Dutch museum is dusting off a rare collection of prints by Andy Warhol of female royalty, made shortly before the pop art icon's untimely death 36 years ago.

Entitled "Royal Edition," the exhibition at the stately Het Loo Palace in Apeldoorn will feature 16 prints that Warhol made of reigning queens.

Denmark's Crown Prince Frederik will become king on Sunday after the unprecedented abdication of his mother Queen Margrethe, with more than 100,000 Danes expected to pour into Copenhagen's streets for the historic event.

The 55-year-old future monarch is hugely popular in Denmark, with 82 percent of Danes saying in a recent poll they think he will make a good king.
