What to observe
Photograph and measure one-tooth, tall, two-tooth, and low forms under shared conditions, and record the intent behind each variation.


Thinking as a collection
A small numbered series can become a clear collecting unit across form, material, motif, and year.
Before buying or displaying
This guide is editorially informed by classified public web, social, collection, and market information. Verify an individual work's place, maker, date, and specifications with primary sources such as its maker or holding collection.
Six fields to check: maker, form, paulownia, finish, hanao, and dimensions / condition。
Editorial note for this page
