Kerry-Anne Walsh, in The Stalking of Julia Gillard: p.248 “Creeps on the internet such as Larry Pickering, have been spewing bile about Gillard and the AWU for months. They have gathered supporters and spawned similarly disturbing websites, sprouting outrageously misogynistic and defamatory allegations against the PM, usually showcasing sickening anti-Gillard cartoons."
Julia Gillard also refers on p.105 of her autobiography to "the pornographic cartoons by Larry Pickering."; and I think Anne Summers also referred to it in her book, The Misogyny Factor.
I did say 'the Pickering name' in my original comment - guilt by association.
