Dick Frizzell's famous Mickey to Tiki Tu Meke painting had some of the elite of Maoridom hopping mad in 1995.
A trained animator, he painted the watercolour for the Life Education Trust children's charity in 1995.
It sold for $4000 then, but is expected to fetch between $60,000 and $120,000 during an online auction on the Ocula Black marketplace site which closes on May 14.
Frizzell spied the watercolour - thought to be the country's most recognisable and reproduced artwork - hanging in the auctionhouse yesterday, and it was like meeting an old friend. Still, he was taken by surprise by the size of it.
"So that's it. Something in the back of my mind tells me I did a smaller work. The whole thing's got me bamboozled," he joked.
