Antique Slag Glass Table Lamp, Exceptional, 6-Sided, 30 Tall, No Cracked Panels

Here is an absolutely beautiful antique table lamp made in the 1920s and having six amber slag-glass panels, plus six more above. It stands 30 tall, and the base, which seems original, is brass and very intricately etched in a, Art Nouveau manner. There is no damage to the shade… Cannot find a maker.
