Art deco bowl in marbled glass paste signed daum nancy 1920

This superb bowl is signed daum nancy. It is a delightful empty-pocket bowl in marbled glass paste in shades of blue and yellow. This marbled glass is silky and delicate, it traps bubbles in the glass. This piece was made by daum at the beginning of the 20th century, as evidenced by the signature "daum croix de lorraine nancy". In good overall condition, it measures 12 cm in diameter X 7 cm. I note scratches from use.
