Forbes’ New Fine Art Picture Gallery, Corner of Main and Timber Streets, East side Public Square. I am now prepared to take all kinds of Pictures, which in beauty and perfection of style will vie with any in the west. I have spared neither time nor expense in fitting up my rooms, and now would cordially solicit the patronage of the citizens of Knoxville and vicinity. I have constantly on hand an assortment of cases of the latest styles, lockets, breast pins, earrings, &c.
