Deletion of Leonid Efros

Comment: the claim that he painted and drew members of the British royal family is verifiable and I fail to believe any old artist would be allowed at short notice into the royal residences. It's likely from the sources (and stated on his website) that his work is held by more than one important Russian art gallery, which would be a criteria for meeting . Because he is Russian and the main events took place pre-internet, other sources will be more difficult to locate (though likely to exist) so my view is we should give the benefit of the doubt and seek to improve the article
