Hot damn, that's a nice chocolate bar wrapper. It's from Loom and Honest Chocolate, two South African companies, who explain the design to The Dieline:
"In August 2012 we ran a crowd-sourced design competition on 10and5.com (a local design design website) and invited creatives from around the world to design a unique chocolate wrapper for us. In just 6 days we received over 115 local and international entries from Cape Town, Johannesburg, Durban, Namibia, Amsterdam, Toronto and Paris.
The winning design came from Cape Town based illustrator, Miné Jonker. She runs an agency called Studio Muti."
