Prince Andrew of Greece and his family

You can find it in an old issue of either the Sketch or the Sphere as well.

Prince Filip and his cousin Michael of Romania :

from wich website do you have this picture ?? are there more of them

 a lovly picture

To answer your question, I did not find this pic in the old threads of the forum or a website but just in this book from Arnaud Chaffanjon: " Stories of Royal Families, Victoria of England, Christian IX of Denmark and their descendants, from 1800 to today. " However, I did not think it was as rare as this.

They are quite rare..

Both cousins are still alive today. :-) Even though Philip looked quite frail recently.

KarlandZita,
That is a great photo, where was it taken and when?

Prince Filip and his cousin Michael of Romania :

There is also another picture from the same event with Princesses Theodora and Margarita (Philip's sisters) and Mihai's mother Princess Helen. The photo was taken in 1929.

In 1929, indeed, at Castle of Sibiu in Romania.

 I wonder which of his cousins Philipp was the closest and with whom he got the best ?

Dou you mean his Greek cousins?   Philip, because he was raised and educated in Britain, he had very little contact with many of his Greek relations.  He was close to Marina because she was in England - and she was good friends with Lady Zia Werhner whose son Alex was one of Philip's closest friends.  (Alex was killed in the second world war).  Zia's sister Nada was married to George Milford Haven, Philip's uncle, who was his legal guardian  - thus Philip was brought into the circle that included the Werhners and the Mountbattens - this also brought Princess Elizabeth into the orbit because she was a childhood friend of Georgina Werhner (Alex's sister)  and the Queen was good friends with Lady Zia because of a common interest in horse racing.
People tend to forget about this connection in terms of Elizabeth and Philip's relationship. 
George Milford Haven's son, David, was also in this group, and was Philip's best man, but after his divorce and remarriage, the two were not as close.

I wonder which of his cousins Philipp was the closest and with whom he got the best ?

The closest in age was King Michael of Romania. The cousins still kept in touch.

Thank You, Eric Lowe and Marlene for your infos.

Here a picture of Princesses Margarita, Theodora, Cecile and Sophie at the wedding of Louis and Edwina Mountbatten in 1922 :

There was a news reel made of this wedding. The sisters followed the couple, while Queen Alexandra and Queen Mary followed...

Yes. Although it did not go to talk more indeph about the realationship. None of the sisters appeared in the program, even though Sophie (Tiny) was still alive then...

The closest in age was King Michael of Romania. The cousins still kept in touch.

Anyone know what were the relations of Prince Philipp with the two sons of his cousin Olga, Alexander and Nicholas of Yugoslavia who were roughly his age?
