Rosenthal Coffee Pot -Hand Painted

A vintage -I would say 1960s- Rosenthal white coffee pot with blue lines. The interior is clean and there are no cracks, chips or crazing. I was told that it was designed by Ambrogio Pozzi but I don't see any marks indicating that it was; it may be part of their studio-linie collection but it is difficult to read the impressed marks. The pot is 7 5/8" tall to the top of the lid and 4 1/4" wide without the handle.
