Cost is the tag name of a graffiti writer who, from the early 1980s to the mid-1990s, blanketed New York City and the surrounding metropolitan area with his wheatpaste stickers, spray paint tags and paint-roller pieces. Cost, whose real name is Adam Cole, is perhaps most widely known for his collaboration with another New York graffiti artist, Revs.
Cost and Revs became well known in the early 1990s, when, on any given block in Manhattan, a passerby could spot the duo’s wheat paste tags posted on the back of the Walk/Don't Walk street-crossing signal. On these wheat pasted papers, Cost and Revs printed in bold black ink intentionally obscure messages such as Cost fucked Madonna or Suicide Revs. Later they collaborated on large, bold roller pieces on highly visible walls, subway embankments, and advertising hoardings.
When asked in 1993 by a New York Times Style reporter what it all meant, Cost said, "If you could give us [Cost and Revs] the meaning of life, I’d give you the meaning of us." At that time the posters included a phone number; those who called heard a woman's recorded voice repeat their questions back to them: "My intuition tells me that you're asking yourselves who are Revs and Cost and what are they doing? What is it? What does it mean? What does it mean? What does it mean?" 
Cost and Revs continued to write in New York City with impunity, highly visible examples of the graffiti that Mayor Rudolph Giuliani was determined to eradicate. One letter writer called Cost "probably the worst graffiti vandal in the history of New York."
In 1995, though, Cost’s luck finally ran out when police caught him tagging a mailbox. In court, the judge estimated that Cost had done over $100 million in damages but only fined him $2,126 and ordered him to do 200 days community service removing graffiti. That run-in with the law eventually led to Cost’s bowing out of the graffiti scene. Revs, however, has gone on to expand on his art and even operates in a legal arena, making headlines recently for creating public, steel sculptures. Cost was again nabbed October 4, 2014 by NYPD. He was charged with criminal mischief, making graffiti, and possession of a graffiti instrument. He was released on bail.
Starting in 2010 Cost made a return to the streets, once again covering the city with wheatpastes alongside new partner ENX Instagram account. . In addition to his trademark blanketing of the city, this comeback also includes a popular Instagram account.
