The below teapot is nice, but the level of detail and ostentatious naturalistic details has decreased, but this might just be the fashion of the time...
I guess we might never know for sure which Charles Fox made this teapot, but by the looks of my teapot, Charles Fox II was firmly rooted to his father's designs, so there we have it. My guess would be that Charles Fox Senior made the teapot from 1822. But that is only a best guess.
