Vintage 1980s Rosenthal Studio Linie Terra Series Dessert Bowl by Wolf Karnagel

This is a Studio Linie porcelain dessert bowl made by Rosenthal Germany as part of the Terra Series by Wolf Karnagel. The piece is glazed in grey with blue linear detailing around its bottom. I have three of these for sale, price is for one bowl only. Each bowl measures 4 3/4 in diameter by 2 in height. The underside is stamped Rosenthal Studio-linie Germany. I believe that this bowl was produced during the 1980s. Each bowl is in excellent condition with no signs of use. This Terra grey glaze with cobalt blue linear detail appears to be very difficult to come by - superior Rosenthal quality!
