Vintage Beauce Blue Wave Teapot Set

Great retro teapot with matching cream and sugar set. Lovely subtle wave detail with speckled purple/ almost black wash. Marked 706 on bottom, no other markings I can find. Crazing, some pits on teapot lid and bottom of creamer - still very nice set. Teapot measures approximately 11.5" long with spout and handle, 8" wide, 5.5" tall.
