What to observe
Separate what a card verifies from what it infers, and note who prepared it. Do not erase uncertainty; label it.


Thinking as a collection
A certificate is not decoration. It is a record that travels with the work, and bilingual notes help future international readers.
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
This is a guide for observation and comparison. Historical attribution, repair, conservation, and wear safety vary by object, condition, and environment.
