Hello! I have a SAtsuma moriage creamer with dragon and immortals design. I have narrowed the mark down to the artist SHozan. there is also a tiny mark/signature inside.

I dont know what the tiny mark is, a signature? hand painted on the rim.

I talked to a local dealer who said this item was only worth 100$ retail. no way.

Id like advice, where I can possibly sell or get more specific details.

thank you!!
