** FILE ** In this Monday, Jan. 12, 2009 file photo, Los Angeles street artist Shepard Fairey poses for a picture with his Barack Obama Hope artwork in the Echo Park area of Los Angeles. Prosecutors in Boston have dropped 14 vandalism charges against Fairey, 39, who created the “Hope” poster of President Barack Obama. But the Suffolk District Attorney’s office said Tuesday, June 2, 2009 that it is leaving open the possibility of prosecuting Shepard Fairey on 13 other pending cases in Boston.
