Thanks for the photos!
It has been a surprise to see Count and Countess de Limburg Stirum attending the event. They looked happy and relaxed. I wounder why the website referred to Countess as Archduchess Marie Christine. She is supposed to have her husband's title, isn't she?
Yes, she is; but by marrying him she didn't lose her former titles, so now Marie Christine is Her Imperial and Royal Highness Countess Rodolphe de Limburg-Stirum, Archduchess and Imperial Princess of Austria and Royal Princess of Hungary and Bohemia.
