This is one of the Ezekiel's Wheel illustrations used in the movie.It is based on "Ezekiel's Wheel" from M. Merian's "Iconum Biblicarum" (1627), however in the original, the "wheel within a wheel" and the 4 cherubim are reversed.Notice the rip in the top of this illustration compared with just a small hole in an extra Ezekiel's Wheel illustration prop. This was probably meant to have happened when John Koestler pulled it off the wall in the trailer where it was hanging.
