Greville 
was an extremely talented commercial artist and indeed one art valuer in London 
reckoned Greville was a better artist than Margaret.
 
They were not married when left for Brasil in late 1951 and in fact did not marry 
until 1980. They lived together in São Paulo using the name 'Mee' and later 
in Rio de Janeiro in what some said was an 'open marriage'. It certainly was a 
relationship that suited them as each could pursue their own interests and make

of Arts and Design at a new address in Kings Cross, London
