Is this Hongxian?
The side picture is too small. Please try to get something near 100 kB. Also, partial views of the blue decorations on shoulder and along base, please. A top view showing the interior just inside the mouth is also required.
FYI, Hongxian marked items were mostly made later, in the republic period. It is virtually impossible to tell for sure whether they could be genuine Hongxian by the decoration, as this period lasted for less than three months. Not enough to develop its unique style.
