Asian antiques, Imperial Dragon Chinese cloisonné tea cup & saucer

We acquired this lovely antique cloisonné set from a wealthy local estate. The cup and saucer are both in very good condition. They were made around the turn of last century. The cup is signed in Chinese characters.  Examining the Dragon you will observe that it is yellow which was the color reserved for the Emperor and also it is the most desired five claw version. The execution of the detail is very fine.  It has obviously never been used and in excellent display condition.
