A rare Fritz Heckert Art Nouveau Vase

This vase made by Fritz Heckert, was designed by Otto Thamm ~1900 and it's shape is numbered 538/5 Th86 in the Heckert design book, kept at the Archive Jelina Gora. Details may be found in the book 'Fritz Heckert' by Stefania Zelasko pages 186.303 and 187.305 and in V. Schorcht 'Umsponnen, Vernetzt und Gekaemmt' page 141. My vase is made of clear glass, threaded with thin blue threads, densily covered by silver-yellow papilon spots, pulled into waves, the vase with six identations and highly iridized glass. It's shape reminds onto JIP type designs, here the mouth is shaped by three orchid like long petales. It stands H=28.5 and D=16 cm.
