The future belongs to the few of us still willing to get our hands dirty.
"Designed by Roland Reiner Tiangco, Dirt Poster requires your participation to complete it. The back side of each poster is covered with a layer of ink, which you need to “paint” onto the front side the poster, to reveal the message that has been spot-varnished onto the paper. Awesome! The poster is limited edition and can be bought for $80.
