This is an original matte painting study done for Indiana Jones and Temple of Doom by ILM matte artist Mike Pangrazio. It also came with the action live photo used by the artist for reference. Its cool to see that the drawings of the characters are almost identical to the photo, as for the shadows and lights on the rocks.
Three different matte artists worked on the final matte painting. Most of it was done by Mike Pangrazio, and final details were done by Caroleen Green (as Caroline "Jett" Green) and Christopher Evans.
