Gasp for air — this is so amazing! As Sub-Studio explains the Dirt-Poster:

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.

The future belongs to the few of us still willing to get our hands dirty.
