A Fish Dish from Portugal

This one I love. It is a dish made by Secla Portugal. I think this one is pretty old but not sure. If anyone has any information then I would love to know about it. It is about 12.5 inches long so a nice size. It has a different fish on each side. The blue color on them is amazing. Wish I could keep it but I will be selling it on ebay next week. Hope you enjoy the pictures.
