ESPO is Stephen J. Powers (born May 25, 1968), a New York City artist who at one time wrote graffiti in Philadelphia and New York under the name ESPO. Through Commisions the artist shows us how banner style art works. In December 1999 Powers was arrested at his home for graffiti vandalism. Powers was a Fulbright scholar in 2007. He used the grant to create murals in Dublin and Belfast’s Shankhill area, with the assistance of local teenagers.
