The cover of OZ (1971) at top was using a drawing by Norman Lindsay (1879-1969)— a famous Australian painter, artist, cartoonist who never shied of showing the naughty bits. 

Lindsay's frank and sumptuous nudes were highly controversial. In 1940, Soady took sixteen crates of paintings, drawings and etchings to the U.S. to protect them from the war. Unfortunately, they were discovered when the train they were on caught fire and were impounded and subsequently burned as pornography by American officials. Soady's older brother Lionel remembers Lindsay's reaction: "Don't worry, I'll do more."[3]

This was the spirit then... and OZ was at the forefront thereafter, till 1973... Our though are with you, Richard Walsh.

"I think it's important we understand what kind of a person he was. He was unafraid, supple-minded, he was open to new ideas, he was adventurous, he was also charming. And we haven't got that many charming men."

Greer said it would take a while to work out what legacy Neville left behind as "he did something that many of us didn't do" in returning to Australia.

"The thing that was important about the way he thought was he always welcomed the future," she said.

"He looked forward to the new. I'm afraid I'm not really like that, I'm kind of a bit suspicious of the new. I used to tease him and say that he was the ad man for the revolution, because he didn't actually have any ideology. His ideology was endlessly supple, but in some ways that's important, that you are open to new ideas in that way, and not doctrinaire like me."

Curiosity and expression of it are the main essences of humankind...
