I recieved a notice from one of my favorite printers that they are donating 100% of the proceeds of this postcard pack to clean water. That means not just the profits; they are donating the entirety of the purchase price of the pack. I can vouch for the quality of Artifact Uprising's prints and postcards. They consistently impress me with what they do. They also link the charity directly in case you just want to help, no carrot needed.
