I donated one of my Storks prints to Illustration Rally's Japan Tsunami appeal. It's now on sale in their Ganbare Nippon Etsy store along with lots of other pieces donated by artists and illustrators. 100% of the sales will be added to I.R's appeal on Just Giving
Visit http://www.etsy.com/shop/GanbareNippon to see all the work available. There's something for everyone, from £3 postcards to £150 original drawings.
