Vintage 1960s ARABIA of Finland Fish Shaped Platter Wall Decor by Kaarina Aho

Vintage Ceramic Fish shaped appetizer serving board, chop board or wall decor – “Kala Alusta” Made by ARABIA of Finland with design artwork by Kaarina Aho. It has been described as Raija Uosikkinen’s design, but I am not certain. 
Measures approximately 12″ long by 7.25″ tall. In Harmaa or Dark Grey-blue. If you look closely under light you can see the fins and scales. They are difficult to photograph. Very nice pre-owned Mid-Century Modern piece! 
There is on small area that appears to be scratching near the bottom of the front of the fish. NO chips or cracks. 
*This color is EXTREMELY rare and hard to find! I only found one more like this one online.
