So let's start fresh -- with a question:
Which artifact below comes from Mexico (Olmec culture, circa 1000 BC) and which from China (Shang culture, also circa 1000 BC)?


Note that both are from the same time period, both are carved in jade -- and jade was precious in both cultures -- and both show the "cleft-head" pattern.
