A mural showing Lenin joining the hands of a soldier and a white and coloured worker painted by Senor Diego Rivera ( the Mexican artist ) has led to his dismissal from further work at the great Rockefeller Centre in New York - members of Mr John D Rockefeller's family took exception to the painting and an ultimatum was delivered to Senor Rivera which insisted that he must change the fresco or cease work - so far the artist ( who is said to have pronounced Communist leanings ) has refused to alter his work and Mr Nelson Rockefeller ( grandson of the oil magnate ) has ordered the fresco to be covered - following the incident work which Senor Rivera was executing for a motor company in connection with the Chicago World Fair has been cancelled - photo shows Senor Diego Rivera and his wife at their New York home after the artist's dismissal. Wife is Frida Kahlo. May 17th 1933
