enamelled copper dish from Italy

I collect enameled copper, mostly from Italy

There are 3 major sort of brands that I know of Laurana, Studio Del Campo and Paolo di Poli but surely there are others

One of which I found today iGuzzini (very famous for lighting) began in 1959 as Creazioni Harvey and they made rame d'arte (copper art)

I believe this piece might be from them, most del Campo pieces seem to be marked and neither Poli or Laurana did this abstract type design that I know of

Surely somebody here knows more than I about this art ;-)
