Anotations

Scope note:

Proofs designated for the printer who produces an edition of prints, occasionally marked P.P. Sometimes the same as the bon a tirer proof for the edition. Printers' proofs are generally identical to impressions of the regular edition except for annotations identifying them as a proof. They can also be used as galley or page proofs on which printers and typographers can make queries and corrections for the client or artist to check, mark, and return; for this use such proofs are usually stamped "MASTER PROOF" or "MARKED SET."
