A Jensen Bowl Gets a Third Dimension In 1926, the Danish silversmith Georg Jensen designed a fruit and flower bowl decorated with acorns and oak leaves. The piece, which was never produced, was known as a jardinière. It embodied an Art Nouveau style that was giving way to the geometric abstractions of Art Deco, speculated Anne Mette Müller-Krogstrup, the head of the silver department at Georg Jensen Inc. And besides, Mr. Jensen was busy hobnobbing in Jazz Age Paris as well as attending to his many commissions. This year, the sketch was selected from the Jensen archive of more than 12,000 drawings, and after six months of meticulous hammering was transformed into a 16.6-inch-high masterwork ($175,000). It can be seen through Tuesday at the Georg Jensen boutique in Manhattan. Half a year to produce a vase? "It was extremely detailed and complex," Ms. Müller-Krogstrup said. The silversmith even traveled to Mr. Jensen's original home in the west of Denmark to collect acorns to use as authentic models.
