For what its worth I recognized this vase immediately. There is a dealer in my mall that has a large paragraph above a pair of these which have black bases...I think you call them pilths in europe. While I forget the guy's name in the paragraph, he was influenced by Lalique when he worked at or for Etling at which time he set out on his own & produced a few patterns in Deco style. Whether the dealer knows what he is talking about I don't know, however I am 100% positive this is the exact vase as his pair only minus the black bases. Ken
