Nick Marzullo climbs the stairway of his Humboldt Park apartment into a cramped attic virtually wallpapered in stickers. Tiny filing cabinets are stuffed with markers and crayons. But this is no playroom for Marzullo’s 11-month-old—it’s business. The ministudio is the headquarters of Pawn Works Sticker Club, an organization that produces artists’ sticker designs and distributes them through vending machines to give the artists a promotional boost.

Marzullo became interested in stickers at an early age, collecting Disney decals at the age of three. “I try to be on the next artist in the street-art world and buy prints,” he says. “I’m a collector at heart, so I have flat files and stack everything.” His home currently displays repurposed signage by Skewville, paintings by LA-based visual artist and music producer Teebs, and other street artists.
