An extraordinary pair of of Chinese export porcelain teapots, made for the American market, decorated with a central spread eagle under a halo of gilded stars, surmounted by the monogram JMC. Made for John and Margaret Christian of Reading, Berks County, Pennsylvania. The couple was married in 1808. The form of the teapot is after English silver and porcelain types of the period, and, the finely rendered grapevine border is most likely after English porcelain decoration of the time.  Very good condition. Circa 1810-1815.
