The "Holy Grail" of teacups that was made during the Ming Dynasty - 500 years old.
It is said that only 17 of such pieces are in existence, of which only 4 are in private collector's cache and the remaining in museums.
The Rooster cups as they are called, are decorated with a cockeral, hen and chicks grazing amidst a beautiful scene of flowers around the cup.
The porcelain is translucent.
The porcelain cup is painted in underglaze blue and overglaze enamel - Doucai style.
