First of all I love the look of the lamp!
Second, there was a large antique importer near us that brought in lots of "reproduction" pieces (furniture, lamps, decor pieces, etc that they stated were reproductions) in the late 90's to early 2000's. Although gorgeous to look at, when inspected closely by folks like us, we would see the signs that they were in fact reproductions.
This reminds me of some that I saw at their place. Still gorgeous...just not antique. Most were metal that were painted to look like the aged patina one would see in an older piece. I suspect this is like those...which have been imported by dealers across the country.
Hope I am wrong...but suspect this.
