Dish in hard pressed glass

Beautiful dish in hard pressed glass. We believe it is either Danish or Finnish and in beautiful blue/transparent colors. It is signed with Sea 60/10, which we are 99% sure is the signature and that it was made in the 10th month of 1960. It is well made and very beautiful. 26.5 cm in diameter, 4 cm in height and weighs 1570 grams. No chips, cracks or other defects, but with normal wear and tear, a few superficial scratches after signs of use. Will be packaged securely and shipped with insurance.
