A super vintage Rosenthal Studio-Linie (West German) white porcelain ornamental dish...
It dates from about 1985 and is modernist and minimalist and retro in style. It's bright white glossy glazed with a simple grey line drawing illustration with gold gilt accents. The water lily drawing is stylised and minimal and very much like pieces for Rosenthal designed by Finnish designer Timo Sarpaneva. A simple rounded square shaped shallow bowl or pin dish. 
12.5 wide x 3cm tallest at the corners - a nice size for nuts if used as a shallow bowl. Stamped on the base with the Rosenthal Germany logo (with a dot which should date it to 1985).
Very good condition with no chips. A couple of fine marks to the white.
