Photograph of a sketch in oil colours of Neptune astride three white horses as he hands his crown to a male angel wearing a winged helmet. Britannia stands on the right side of the photograph, placing her hand on the head of a lion who stands behind her. She holds Neptune's trident, signifying the resignation of the seas to Britannia.

The sketch by William Dyce was made in preparation for the fresco 'Neptune resigning the Empire of the Seas to Britannia' at Osborne House.
