That Surreal Portrait

Saw this graffiti along King George St., and found another of this black and white portrait like what you've seen in here. I found more of this in different places and I wonder what's this portrait was all about. This is all I can offer you today my friends... Today is my free day and free day means SLEEP!!!

Happy Sunday Everyone!


EDIT: My friend Galia here said that it's a poem. Wow!
