It was labeled "Innocence."

But the photo of a woman with an exposed breast -- from a historic painting hanging in the Mercer County Courthouse -- might be construed otherwise, according to Mt. Lebanon Public Library officials, who asked photographer John Flatz to replace it with something else.

He refused, and thus began a tug of war that has, for now, ended in a draw.

"Innocence," a portrait in the classical style of a woman in slight deshabille, robes flowing off one shoulder, is in the library's exhibition of Mr. Flatz's architectural photographs through the end of February, but "the possibility exists that it could be challenged," said Cynthia Landrum, assistant director and spokeswoman for the library. The library's director, Cynthia Richey, is traveling overseas.
