A Stephen Folch polychrome chinoiserie dinner plate. 
I haven’t found much by him, his factory didn’t last too long , running from 1819- 1828. This has some super,  vibrant colours along with a butterfly which is always a plus in my book and it has a wonderful back-stamp too ! 
Diameter : 25 cm
In good condition with crazed glazing, all in all  a lovely decorative piece, would look great as part of a wall collection.
