Once again, Natronbomb is auctioning off some cool mixed media pieces for charity. This one is a 22″ x 30″ spraypaint/stencil print with an edition of 5 (each is totally unique). 100% of the proceeds will be donated to the World Wildlife Fund, specifically benefiting keystone species’. Additionally, the three highest bidders will receive one of these new skeletal prints he just completed. It’s a cool thing for a great cause. Check out the auctions at Ebay.com.
