This is a painting.
Within the painting, are several other paintings. Keith Haring, Roy Lichtenstein, Damien Hirst.
But, tilt your head and the paintings move from within their fixed position inside the canvas. Perspectives run amok and you feel as though you're traipsing through an M.C. Escher-designed art gallery.
"Then it mustn't be a painting!" some bold, Oliver Twist-esque naysayer might utter.
