Now this is a great project... Founder of the program, Anna of Sub studio, sent this link across and I was instantly taken by the idea and the quality of the prints. Basically artists submit a print to be sold, choose a charity to which 15% of the money will go and ta daaa. There are some great artists and great prints to be bought here. These are some of my favourites...
Truth/Mystery by Sam Chivers
Birdies by Amaranta Martinez
Forest Lady by Karolin Schnoor
Wanderlust by Linda Kim
Lots more on the Working Proof website... go forth and buy some peace making prints!
