This is a vintage ashtray or decorative shallow dish made by Rosenthal Studio Linie and dates to around 1982.
It was designed by the American artist, Dorothy Hafner - and the pattern has already become a design classic.
This pattern is called Love Story - and it is a beautiful colourful geometric design. Love the little fish on each side swimming about and smoking a wee pipe
The dish is triangular in shape and is about 1 3/4 inches in height and is 6 1/2 inches on each side.
It is in good vintage condition - a tiny little restored nibble to the bottom edge on one side (you cannot notice this on display - only when you are looking for it) - this wee issue with the condition is reflected in my asking price.
