At one time the West, represented by this doll, loomed large vis-a-vis the Maoist regime. Now, however, the scale might be changed somewhat as China's economy grows and grows and grows.
There is such incongruity here, Tim -- you contrast big vs small, political vs apolitical, drab vs. colorful. The fact that the big doll is half-dressed and seems to be thinking about relieving himself in the presence of Mao, etc., is very amusing as well.
