Kenner chose an image of the Rebel Soldiers as they waited for the pending AT-AT attack on the Rebel base.  In the image you can see several Rebel Soldiers and a Radar Laser Cannon.

 

Expert airbrush artists at Kenner altered the image, taken in Norway, and have increased the brightness of the sky, which is notoriously difficult to capture with a highly exposed white background.  You can see the original size of the picture at the bottom of the image and that it has been extended at the top, by airbrushing additional sky and snowy background.  The cardback image utilised this extra area and the bubble area was placed over the ‘non airbrushed’ portion of the image.
