This listing has a beautiful McCoy Graystone teapot in the larger 6 cup size!
It's marked on bottom: 1418, McCoy, Lancaster Colony (mark), USA.
Teapot has excellent and somewhat unusual colors -- the brown drip color is darker than usually found in this line. It also has a matte finish rather than the shiny over-glaze that is most often found on Graystone items.
It has some typical McFlaws -- production pin-pops, a non-color spot on inner rim and some glaze pops at bottom dry (setting) ring -- all are production and none are detrimental to use or to appearance.
Teapot looks new and unused!!
