Bon a Tirer (BAT)

Before a publisher starts printing an edition, the artist will mark the proof 'BAT' or 'Bon a Tirer', as the image that the printer uses as a guide for the edition. It is marked Bon A Tirer (French for 'good to pull') or abbreviated to Bon or BAT in the lower left, beneath the image. These remain the property of the print workshop.
