Hi m,
it´s a WMF powder decorated piece from around 1970; shape possibly designed by Cari Zalloni.
The no longer working link I posted some time ago showed the exact piece with a WMF sticker of that time.
Meanwhile...
shapedecorSince WMF didn´t continue their Ikora line longer than the early 50´s these 70´s pieces simply aren´t Ikora,
no matter how similar or not the technique or appearance may be. The term ´70´s Ikora´ IMHO therefor is
a misleading term, which doesn´t do the complexity of most real Ikora pieces justice...

edit: If the vase in question has a ground and polished top rim and isn´t a lampbase or part of a lidded box,
it´s quite unlikely to be WMF Ikora.
