Matte Painting : Mario Larrinaga
There are plenty of excellent matte paintings on that Warner Bros film. Most of the upper part of the buildings and skies on the street scenes were enhanced with matte paintings.
The color image shows a matte painting by Mario Larrinaga. I can´t assure he was the only artist on the show, probably there was another matte painters contributing. In fact there was at the Warner Bros matte department such a great artists as Paul Detlefsen , Hans Bartholowsky or Chesley Boestell.
