Full length portrait of Sir Alexander Keith. The subject is seated on a grey horse with golden saddlery; he sits before a crown, rested on a red cushion with gold embroidery and lifts his hat in salute. Flanking the figure of Alexander and set back in the shadows are the Knight Marischal's esquires; the Lord Francis Leveson-Gower is mounted to his left, bearing the Sceptre and to his right, George Douglas bears the Sword of State. In the left foreground George Campbell stands at the foot of a column, wearing highland dress and carrying a sword and shield. To the right of Alexander a young woman stands looking towards the viewer with her hands clasped to her chest, and a dog laid at her feet. Standing between the figure of the young woman and George Douglas is the figure of a man, arms raised staring wide-eyed at the golden mace of the Court of the Exchequer, which is stood against a wall to the far left.
