A lawyer says the artist who created the "Hope" poster of President Barack Obama will plead guilty to some of the vandalism charges he faces in Boston, while other charges will be dropped.

Shepard Fairey was in Boston Municipal Court on Friday. His attorney Jeffrey Wiesner says they are finishing details of the agreement with prosecutors, but says Fairey will plead guilty to some of the 13 vandalism charges.

Fairey, of Los Angeles, was arrested in February when he was in Boston to kick off an exhibit.

Prosecutors have already dropped 14 charges that claimed the 39-year-old artist placed stickers on public property.

Fairey says he dramatically changed an Associated Press image to make the "Hope" poster. The AP has said the uncredited and uncompensated use violates copyright laws.
