This is a nice ornate slag glass panel lamp by the Pittsburgh Lamp Glass and Brass Co., c. 1920. This lamp carries it's intricate design in the base and shade. It is a smaller size lamp that lends itself to use on a night stand, desk or any other place where a smaller stature lamp is needed. The lamp is 20" tall and the shade at the bottom measures 12" X 12". The lamp is signed on the underside of the base, under the base weight.
