There are surely not many authors who can write children's books - packed with paintings and drawings, sketches and photographs - based on memories of their childhood friends who just happened to be artists Pablo Picasso and Joan Miro.
There are probably even fewer who got away - almost - with biting Picasso or who visited London Zoo with Miro as a guest of the then-mammal keeper, Desmond Morris.
It means Antony Penrose is truly unique. The son of English artist, historian and poet Sir Roland Penrose and American model-turned-photo-journalist Lee Miller, Penrose is here this month as a guest of the Decorative and Fine Arts Societies of New Zealand, which aim to promote and preserve the arts.
He's speaking about his playmates Picasso and Miro and the two delightful books he's written, ostensibly designed to whet young appetites for art. The books are quirky, charming and all true, including the story of how, one day while playing with Picasso, he got "over-excited" and bit the influential Spanish artist.
Picasso's response? He bit Penrose straight back and Penrose's parents didn't bat an eyelid.
"Had the incident happened today, child protection services would have been called in, Picasso would have been dragged off by the police and it would have been reported by all the papers but this was the 1950s, when parents regarded it as an object lesson in consequences," says Penrose, who arrived in New Zealand after a Sydney stopover to meet his new grandson, Theo. "I can tell you, I never bit anyone else, ever again."
From the books, it looks as if Penrose had a magical, bucolic childhood spent on his parents' Farley Farm in Sussex. But pictures can be deceptive. While his childhood was certainly stimulating and packed full of intriguing experiences, Miller was deeply affected by her experiences as a photo-journalist in World War II. She battled depression and alcoholism, motivating Penrose to move as far away from home as he could in his 20s.
