The colours are sumptuous! The tray measures 9 1/4" square and features three flag iris flowers and leaves. The background is a wonderful blue green and the blooms are one x typical iris blue, one x golden to butter yellow and one x a complex shade of purple, leaves are shaded in realistic green. The workmanship, and execution of this piece is beautiful. The back is solid black enamel. Now the downside: There are two areas which have fine cracks, I am not an expert in this field so I don't know if this is due to damage, or happened at the time of firing? There is also a small area of damage to the bottom right corner, a minute piece of enamel missing, and also damage to the top right corner, a blemish, no enamel missing. In normal lighting, this damage is all but invisible. There are no marks that I can see, I've owned this piece for 30 years, but have no idea of it's age or origin. Due to the imperfections, I have priced accordingly.
