Expression of irony
I see the irony in this flash. The mannequins are just models (or dolls) and yet, they display such a wide array of art in the form of clothes. In that sense, they are full of life, due to the amount of culture and attention they attract. The worker however, is alive and has a beating heart and yet, has NO life. The mannequins are the ones with life, instead of the worker.
I thought that irony was well expressed.
