Scandinavian blue and white stoneware tea service

Complete stoneware tea service in excellent condition. No defects to report, the pieces are impeccable. The set includes 5 cups with each saucer as well as a teapot. This "öresund" set was designed by the artist signe persson melin for the höganäs keramik factory, which is a swedish house that started in 1909. It now belongs to the finnish house iittala, which specializes in glass art. The service is stamped. And according to my research it dates from around the 1970s.
