Tonsberg Hammered Aluminum Wall Hanging with wood candleholders.

I recently came across this wonderful piece and had to bring it home. The hammered design depicts Scandinavian boats and buildings and almost tells a story. I learned that Gullsmed means goldsmith and I was able to contact a shop that knew of the Ronnings. I have emailed a couple of times to see if this is one of their works or just a piece that traveled through their store but have received no answer. No matter what I love it!
Does anyone have any insight? Would love to know! Thanks
