An antique pair of Kayserzinn vases in highly polished pewter by J. P. Kayser & Sohn AG of Krefeld, Germany, dating circa 1898-1900.
The tall and slender bodies have a reflective warm silver glow ornamented with delicate, natural motifs characteristic of the Art Nouveau / Jugendstil period. The design features overlapping embossed leaves encircling the lower part of each vase; the shoulders consist of a trio of low-relief cyclamen blossoms with stems arching into handles around a petal form rim.
Very good original condition with some light scratches, measuring 11 in. H. One foot is very slightly bumped on one side but does not impact the stability or design. The first vase is marked 10 / Kayserzinn / 4229 / X / P and the second vase is marked U / 15 / Kayserzinn / 4229 / P.
This vase model  is published in Gerhard Dietrich and Eckard Wagner's, catalog raisonné, Kayserzinn: Engelbert Kayser, Jugenstil Pewter from Cologne, p. 172, no. 4229.
