This is a pretty Heinrich (H & Co) Christine Line, “Arcadia” squat teapot. According to the maker’s mark this pattern was manufactured from 1930 until 1939, in the Selb region, Bavaria, Germany. Apparently Heinrich did not make many of these teapots. Replacements, Ltd has one in a similar pattern listed for over $400.
This teapot is in excellent, used condition. Take a look at the pictures, and if you have questions, please e-mail.
