More retro European royals: Astrid, Queen of the Belgians.
Astrid was quite interesting and ahead of her time, a media darling in the style of Princess Diana, but during the 1930s. She also died in a car accident.
She looks a bit like one of the Mitford sisters in this picture.
I first got interested in images of old Euro royalty from my postcard collection. I like postcards of things that no longer exist, like extinct duchesses.
