SYDNEY, AUSTRALIA.- Two decades after his murder, the former Beatle has revealed another of his talents: children's illustrator. When his son Sean was born in 1975, John Lennon hung up his guitars and withdrew into domestic anonymity in the Dakota building in New York, telling wife Yoko Ono to take care of business while he played househusband. However, newly released illustrations, now being shown in Sydney, shed fresh light on "the Dakota years", and prove that Lennon was mentally alert and creative. In all, 16 prints have been released. Drawn for his young son, they show his lifelong obsession with word play and the absurd, familiar to anyone who has read his whimsical books, “In His Own Write” and “A Spaniard in the Works”.
