This hand-drawn digital painting commemorates the Ica stones. The design is based on a few rock-curved drawings for reference, but the human was removed from the dinosaurs' mouth for your comfort. Instead the man is begging for protection from the comet (yes a comet!), hiding under a giant fern. The spots and stripes stayed true to each animal.
You might notice the cross-hatched shorts and sock lines on him -- these ideas came from the original drawings, where similar cross-hatching was used for scales of fish and reptiles. So, did early man wear alligator shorts?
