I like this editorial illustration from the New York Times op-ed, “Throwing Free Trade Overboard.”
This teacup is a visual metaphor for the Tea Party. Within its circular border is a container ship, carrying goods for international trade. It’d like to set out to the high seas, but it can’t.
Its passage is being blocked by the cup’s rim, which is a representation for protectionism, a backward-looking economic policy the Tea Party-ers are clamoring for.
