Royal response from Their Imperial and Royal Highnesses Prince Lorenz and Princess Astrid of Belgium, The Archduke and Archduchess of Austria-Este on the occasion of Christmas 2017 and New Year 2018.
The reply is in the form of a card in English and also included a family picture of The Royal and Imperial Family.
Such a nice reply!! Do they always send out Christmas replies?
Usually just a card, the picture is rare to get
Hope this helps.
