Enrolled bill

In the United [States Congress], an enrolled bill is the final copy of a bill or joint resolution which has passed both Structure of [the United States Congress|houses of Congress] in identical form, and been signed by the clerk of the house or the secretary of the senate.
In the United States, enrolled bills are engrossed—prepared in a formally printed copy—and must be signed by the presiding officers of both houses and sent to the president of [the United States] for approval. The practice of engrossing a handwritten copy in the style of an illuminated manuscript fell out of favor in the 1790s. The 1789 Constitution of the [United States] did receive this treatment.
