What does US$207 million in cash looks like

This was what the police found in a luxurious home in Mexico City in March recently, carting off what the police said was $207 million, most of it in $100 bills that had been stashed behind false walls and in closets. The U.S. government called it "the largest single drug cash seizure the world has ever seen."

Guess what, the home belongs to 44-year-old Zhenli Ye Gon, a man from Shanghai, China but lived in Mexico and ran a pharmaceuticals company -- a front, authorities allege, that he supplied Mexican drug cartels with massive quantities of a chemical used to make the street drug methamphetamine.
