I think they have sought a fair solution.
This year, in the family have been several important developments that could have been the subject of the card, but for various reasons, this would not have been fair:
A: The christening held in Lanzarote, there were family photo, this might have been the card ... but it had not been fair, Pavlo and Mc were not in christening.
B: In summer,The kings were in Beijing, the family was in July and early September in Greece, but Pavlo and his family were not in Greece, they were in EEUU.
C: In the graduation in May of Prince Fillipos, were the five brothers, but they were not the rest of the family.
They had to choose the most just solution, and I agree, the photo the kings and their five children, is the most just solution ..
