Which is better, calligraphy works with donors or calligraphy works without donors?

It's good to have the signer's calligraphy works. You can collect the calligraphy works of signed donors, which will not affect the value of calligraphy and painting works, but will bring potential value to the works, so the calligraphy works of signed donors are good. The signature is divided into single and double paragraphs, not only the name, year, month or poem of the recipient.
