I've recently come across this picture of Grand Duchess Josephine Charlotte, when still Princess of Belgium, attending an event at the Brussels Town Hall in 1949, during the first visit to Belgium by a member of the Royal Family since WWII (when they were exiled by the Nazis)! It appears she is wearing a small mystery Bandeau Tiara in her hair, which does not look to a known piece from her mother! I wonder if anyone knows about this piece? Could it be an earlier version of one of the Bandeau Tiaras she supposedly acquired for the Grand Ducal Vault?
