From about 1915, this table lamp has a hand leaded stained glass shade. The weighted base has an original dark bronze finish on this unsigned American antique light. The base has an old repair and is slightly crooked, see photos.
We see no damage to the stained glass. Three brass standard base sockets have pull chain switches and are rewired.
Measurements are 20" diameter and 21 1/2" tall.
