This is a yellow ceramic tea or coffee pot with a matching creamer and sugar bowl.
These solid yellow pieces all have domed lids, with ribbed handles and ribs around the bottom. On the bottom, they read the USA and what appears to be a number or date.
The pot measures 9.75" tall including the lid, 10" including the handle and spout, and 5.5" in diameter.
The creamer and lid measure 4" tall, 5.25" including the handle and spout and 3" in diameter, and the sugar bowl and lid measure 4" tall, 4" including the handle, and 3" in diameter.
These pieces are in good preowned condition, but the creamer has a crack on the lid.
