Warhol was questioning the capitalist society.

The only thing the Pop Artists had in common is that we all had been commercial artists in some manner. Lichtenstein was a draftsman; I was a billboard painter, but we didn't work together. I didn't meet Andy Warhol until 1964.

Certainly I have made comments on American society with the various pictures and have done about nine antiwar paintings. But I did them because I was incorporating my feelings into my work.

The worker is the slave of capitalist society, the female worker is the slave of that slave.

It's really questioning where humanity is going, and is there a place for the way we perceive things now? Does that have to remain the same? Is anything constant? The world is constantly evolving, as is humanity. It's really about evolution and taking charge of humanity's next step.

Given the global outperformance of the Australian share market, some investors are questioning the possibility of further gains.
