LEUNE antique art nouveau vase with Virginia creeper

Magnificent antique art nouveau vase, verrerie de leune (1861-1930), unsigned but stamped ln (which corresponds well to this manufacturer) under the base, numbered 3482. Shell shape with slightly narrowed foot, colorless frosted glass with hot-fixed enamel, decorated on one side, leaf and vine motifs with small blue fruits, autumn creeper, in shades of reddish brown, dark shaded green, dark blue, khaki... Interior of the neck pale yellow. 30cm high, approximately 12cm max diameter, 7.5cm diameter at the neck. Very good condition, no notable accident, intact enamel, no major defect to note, a few small traces of time however, rare and discreet scratches, interior very slightly tarnished by use (a few very discreet marks). I think it was originally painted inside, in a gradient, this is no longer the case, it is not annoying however, the appearance is cleaner in fact. About 1kg.
