I think I may have bidded on this item, the decor and general quality looks wonderful. I hope you find a firm attribution, a piece like this deserves one! I would have been interested, thinking it Bohemian really. However, a suggestion from Ivo of America or Bohemia offers two options at least. One would think a museum of some standing has one of these in its archives somewhere! As you say, it goes well with your other similarly decorated piece... the cabinet is great too...
