Nepotism in Portugal? ( Just a funny story )  :)

Hi,
I was wonder if someone knew what represents a reverse design on 2018 Portugal 7,5 euros, issued in name of famous architect Eduardo Soutu di Moura .. ( Design author is A. Siza )
first i tried to find what is ont he reverse, then I started to search in wikipedia - who is Moura and what he built. well , really interesting architect with number of wonderful works... Then I dug in his biography  :)  :)
and .. what a surprise ! - In 1970-s he was studied and worked in the architect studio of A. Siza  :)  : ) ... and.. - BINGO !!! - married on his daughter !
So, there are two great architects in Portugal, who were recipients of Pritzker prize ( 100.000$ + great name) . A. Siza, and his son -in low, Moura ... BTWS, there are no Pritzker recipients in Austria, in S. Korea, in Canada, in Sweden.. But they are two in Portugal. And bioth from the same family..
I`d finish here, but I found later, that in 2017 a 7,5 Euro coin was issued as well, and it was "A.Siza" - s coin .
And designer of that coin was..
yes! - Eduardo S. de Moura !!!!!!!!!  :)

P.S. .. maybe someone help, what is on the reverse of upper coin? ??
Yours, David

It's a lie that Eduardo Souto Moura have married the daughter od Siza Vieira!
Eduardo Souto Moura married with Maria Luísa Marinho Leite Penha.

It's correct that the coin regarding Eduardo Souto Moura work is from Siza Vieira and the coin regarding Siza Vieira work is from the Eduardo Souto Moura.
That was a good choice regarding both have win the Pritzker Prize.

The ‘Eduardo Souto Moura’ coin is only legal tender in Portugal and has the following features:

On the obverse:
In the middle, the stylised representation of a treetop;
On the left, the Portuguese coat of arms;
Around the upper edge, the words ‘República Portuguesa' and '2018’ and the face value;
Around the lower edge, the abbreviation ‘INCM’ and the name of the author.

On the reverse:
In the middle, a classical column representing human construction;
Around the upper edge, the words 'Eduardo Souto de Moura'.

Thank YOu, Eureka !
HA-ha! - I wonder where Russian Wikipedia got such information :)))))
