Vitra-Gesellschaft zur Herstellung künstlerischer Gläser und Fayencen...

I think this might be a rare art nouveau "vase"... it has been designed by Otto Vittali (1872-1959) around 1910 to 1915... at least that is what i think... Vittali was a painter and craftsman, studied at the academie in Karlsruhe and in Munich under Professor Linnemann...

Around 1910, Vittali introduced "new" glasses and faience with metallic finishes after he founded his "Vitra-Gesellschaft zur Herstellung künstlerischer Gläser und Fayencen mit Metalldekoren" in Berlin...

I don't know how rare it is but i can't find this model searching the web...
"Vitra-Gesellschaft zur Herstellung künstlerischer Gläser und Fayencen mit Metalldekoren" means something like "Vitra Company for manufacturing artist glass and fayence with metallic finishes"
