I bought these three small figures. The largest one is 9,5 cm. They are made from a red pottery, with a iridised green/brown glaze.  The features of the figures look very convincing for genuine Han figurines. A known theme in Han ceramics are (court) entertainers. The middle figure seems to play a musical instrument. The right one could be a singer or dancer. Very similar figures can be found (online) in the Freer/Sackler museum, and in the Henan museum.
