This is an antique, early 20th century, hand painted porcelain decanter with stopper, small serving tray and two matching 'stemmed' glasses each with a design of a sailing ship in water during sunset or sunrise that was made in Japan by Noritake. The mark on these in green with an M in a wreath was used from 1911 to about 1921. Nippon is the Japanese phonetic word for 'Japan'. The M stands for the Morimura Brothers who founded Noritake China. The estimate is for the set altogether and is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
