Anotations

Scope note:

Standardized symbols, notations, or other markings applied to objects during or after creation, conveying information such as the object's origin or maker, its authenticity, or a change in its official status. For lettering marked on something for documentation or commemoration, use "inscriptions." For marks inherent in the paper support, not applied as part of the image or work, use "watermarks."
