Featured Sarpeneva bronze Brutalist? bracelet

I picked this up from a flea market because it looked unusual. I noticed it was signed although I couldn't see by whom. Took a gamble for £8.
Anyway it turns out to be Sarpeneva which is a new name to me, made of bronze in Finland.
Am I correct in saying brutalist or is there a better term?. My googling suggests 70s but the dates are all a bit random.
Should I polish or leave it as it is? I'm quite liking it so it may yet be a keeper!
Any information welcome.
Thankyou

 

Sorry that last photo wasn’t good enough.

 

Well if that is Timo Sarpaneva you have a good thing I'd say ..he's well-respected.

I just found out it ain't him, it's by Pentti Sarpaneva. lots on google

 

Looks like it has an applied patina,you could touch up the high areas with a sunshine cloth.

 

I'd call it Brutalist.

Turun Hopea produced many of the same Pentti Sarpaneva designs in silver, the earliest date found in a quick search for the same bracelet in silver was 1969 - Sarpaneva died in '78, but entirely possible his designs continued to be produced...

Personally, wouldn't polish it, looks as it should...

Agreed. It might be lacquered and polishing will really f it up.

 

Which if I'd spelled it right I would have found..........sorry!

 

This is my 1977 Turun/Sarpaneva spoon in the 'Pitsi' (Lace) pattern, I know it was still in production in the '90s:

Very nice!. Presumably Sterling?

 

.830 fineness. They made a lot of jewelry in the same pattern...

Definite texture similarities to the bracelet

 

JMHO. leave as is. artists work with patina to give it more depth.
lovely.

 

I will leave alone! Thankyou
