Trumbull painted the figures from life whenever possible, but some had died and images could not be located; hence, the painting does not include all the signers of the Declaration. One figure had participated in the drafting but did not sign the final document; another refused to sign. In fact, the membership of the Second Continental Congress changed as time passed, and the figures in the painting were never in the same room at the same time. It is, however, an accurate depiction of the room in Independence Hall, the centerpiece of the Independence National Historical Park in Philadelphia, Pennsylvania.
