Overall very good condition. The glass is likely replaced and presents with light surface scratches consistent with age and gentle handling. The mica with some surface scratches and areas of slight flaking, stable. The bronze surfaces with some areas of rubbing, surface scratches, minor edge abrasions, and scattered discolorations throughout. The join on the proper left side of the sconce has been reinforced with solder. With some light surface soiling and minor traces of oxidation to the recessed areas of the design. With replaced screws. A nice example of the model.
