Dirk Van Erp Rivet Base Vented Cap Hammered Copper and Mica Table Lamp. Excellent original patina and mica. Lamp was purchased from the home in which it has been for many years. It is in unusually good condition, it appears dry from the climate in which it resided. It would benefit with a touch of quality wax. We prefer to show the lamp as we found it and can give it a touch of "tlc" when requested by its new owner at no additional charge.
