Change of Theme coming! Butterflies

I'm expanding shifting and changing the Year of the Bird theme towards Flight and Flying and then Butterflies perhaps. So watch for new themes!

Most of the best Butterfly ceramics prints and paintings seem to date to the Qing dynasty?

This pair of double gourd shape vases are "famillerose" overglaze enamels form the Qing dynasty.

I am wondering if the overglazes developed during that dynasty allowing polychrome with richer colors plus the popularity and spread of  "how to paint" huapu books of examples are interrelated?
