Royal response from Her Serene Highness The Dowager Princess de Lippe on the occasion of Easter 2022.
The reply is in the form of a card which on the front has a picture of Her Serene Highness in the library with her dog and inside is a message in English and German thanking me for my Easter wishes.

How can you address her son on envelopes and inside card? I wish to send him a Sympathy card on the recent passing of his mother
