A delightful teapot, probably Jerusalem Iznik. 
Nice hand painted floral & geometric ornament in typical Iznik style & colours: copper turquoise, chrome green, cobolt blue, iron yellow, iron terracotta, manganese purple-brown, all with a surround in stable black pigment.
White, pale body.
1920 - 1950.

Condition: is near perfect - a small chips to rim of lid - see photos.
