Using public street fixtures as printing elements, the artist collective behind Berlin-based Raubdruckerin (pirate printer) produces shirts and bags imprinted with manhole covers, vents, and utility grates. The overlooked geometric patterns and typographic forms of urban signage make surprisingly nifty graphics for shirts. The collective applies ink directly to the streets and prints on-site in locations like Amsterdam, Lisbon, and Paris and then sell their creations through an online shop.
