see my post below, "Pretty Princess Book" (Vhttp://members.boardhost.com/books/msg/1334498710.html) where I talk about the next publication of a picture book on Princess Lilian fron the archives of Princess Esmeralda. And the publication in the end of this year of a new biography by Olivier Defrance on Dora Schleswig-Holstein, the daughter of Louise. This book will have many sensational revelations!!
And I can advance that Princess Esmeralda asked Olivier Defrance to write a biography on her mother. He will have access to all Lilian´s archives and, at last, we will learn why King Baudouin met Léopold III only 2 or 3 times after 1960. This book will be published in 2014.
Have you bought the DVD Léopold III Mon Père? There´s a small book of 50 pages with a never-seen-before picture each page. The pictures were selected always by Princess Esmeralda. You can buy it at the boutique of RTBF if you live in Belgium. (for those who do not live in Belgium go to http://www.dvdfunprice.be/store/leopold-iii-mon-pere-mijn-vader-dvd.html).
Since you like Queen Elizabeth (thank you for the tip by the way!) you might find interest in buying the catalogue of the exhibit held in Brazil in 1910 to celebrate the 90th anniversary of the royal belgian visit to Brazil. Mr. Janssens from the Royal Archives in Brussels was one of the organizers of this exhibit and catalogue. You will find 2 copies in this link: http://www.estantevirtual.com.br/q/visita-belga
They take credit card and 60 Reais is about 25 Euros.
