The concept of this poster is metaphor of the manufacturing symbol as a tank full of sharks. The fins of the shark is the visual play on the slanted roofs. The wave lines represent water but also an architectural roof line. The shark fin are menacing and symbolizes the predatory nature of sweat shops and factories that take advantage of the poor and disadvantage. The smoke stack with the white hand is a visual play on a swimmer in distress at the verge of sharks and signaling for help. The white hand is visual play on the smoke coming of the stacks.
