These concept illustrations for the scene's visual effects shots were likely rendered by production illustrator George Jenson on illustration board. Both depict wide shots of the UFOs circling Devils Tower and a close-up of humans shielding themselves from the bright orange glow. The latter image features the hand-written caption "Effect #4 Cont. Objects close pass camera - area oranges out". The pair is in good overall condition with minimal wear from use and age.
