We'll be the first to say that this slide has not aged well. Rolf Harris toured New Zealand in 1970 and this slide may date from this time. It probably screened in Palmerston North but may also have be shown in Levin's cinema as well, given that this was a national tour. We know from the label that it was screened in Kerridge Odeon cinemas- then the biggest chain in New Zealand. Cinema advertising was often used to advertise the arrival of touring acts from overseas.
Rolf Harris was convicted of twelve counts of indecent assault on the 30th of June, 2014. Victims of Harris's offending (outside of the counts he was convicted on) came forward from his 1970 New Zealand tour.
