The reply is from King Albert II and Queen Paola of Belgium. They are King Philippe's parents. King Albert reigned from 1993 - 20013, before abdicating.
Their Christmas reply is a lovely card. On the front is a photo of the couple, with their 1st and only great-grand child, HI&RH Archduchess Anna Astrid. She was born in May 2016, to the proud parents, TI&RH Prince Amedeo & Princess Elisabetta.
The two signatures are printed on.
