Artists serving time behind bars are raising cash for hard-up kids living in Christchurch's quake-hit eastern suburbs.
Prisoners from Canterbury's three jails are giving their best impressions of Rembrandt, Monet and Picasso to charity.
More than 130 pieces of art, including oil paintings, wood and bone carvings, flax weaving and soap art will be sold in the October auction, with proceeds going to the Youth Alive Trust.
Many of the submissions are from prisoners who participate in prison arts programmes.
"The programmes re-introduce prisoners to learning in a positive and non-threatening way," said Ian Bourke, southern regional commissioner of Corrections Services. "The quality of the work is outstanding."
