Vtg Citrine Yellow Art Glass Vase Unmarked Maybe Miloslav Klinger Zelezny

It isn't marked, but I think this may be a Miloslav Klinger citrine glass piece for Zelezny?. Not certain on that though! CONDITION: Acceptable, used condition! No noted breaks. I wiped down the outside of the vase with a damp rag, but the inside is a bit dusty and I don't have a way to thoroughly clean it.
