Gorillaz designer's art on sale in Bristol
Jamie Hewlett designed the characters in the band's animated videos, for songs sung by Blur frontman Damon Albarn.
He accompanied international aid agency Oxfam to Char Atra in Bangladesh to see the human cost of climate change for himself earlier this year.
The trip inspired him to paint nine huge watercolours, currently on display at the London art exhibition, Under Water Colours.
The work is set to go on display in Bristol, if Oxfam can find a suitable venue.
It is due to be held just weeks before the international climate talks take place in Copenhagen and before the "wave" march in London on December 5.
The march is expected to be the largest march about climate change, and will see a group of cyclists from Bristol taking part.
Rosanne White, who volunteers for Oxfam in Bristol, is one of them.
She said: "I'm really excited about going to London to show my support and so are all my friends.
"There's a lot of interest already from people in this area who are planning to go, so this really is going to be a huge public demonstration on climate change."
Six of the Hewlett watercolours are available as limited edition prints, with proceeds going to Oxfam's work to help people in the region protect themselves from the effects of climate change.
