This has a Lobmeyr monogram scratched in the bottom, but I believe it is Meyrs Neff and dates to about c1905. Looks very similar to several Josef Hoffman designs, and is absolutely alongside his design but could be Peter Behrens. Features transparent enamel florals on a multiple sided wine glass with double horizontal cuts....giving this a very geometric form. Measures about 6 3/4" tall and 2 1/2" diameter across the bowl. A stellar piece for display and a great early example.
