Very Rare Original Mid Century Prototype Production Niko Kralj for Stol Kamnik Bentwood Chair Lupina. Has original Yugoslavian import stamp. Needs some work on one bottom brackets. Looks like it need to be re glued. Some of the wood has peeled a bit. Only a few of these are know to exist and the only ones I found are in museums of contemporary design and art. I’m open to offers. Has a small chip on the back rest.
