Elevate your collection or space with this magnificent vintage cobalt blue art glass bowl, designed by the internationally acclaimed master glass artist Bertil Vallien for Kosta Boda (Sweden). As showcase-ready as it appears in IMG_3398.jpg, this piece commands attention with its luminous, saturated cobalt blue body. The exterior is beautifully wrapped in an intricate, acid-etched or sand-frosted stylized leaf and vine pattern.
