This is one of a set of twelve oval portraits in matching frames of members of the Hanoverian royal family (406587-90 and 401339-46), only six of which are catalogued by Oliver Millar (OM 634-9 and 1218). They would appear all to have been copied from existing portraits of the first half of the eighteenth century. The set was first recorded in Windsor Castle in the 1870s. This is based on (or is the same type as) the anonymous portrait in the collection (OM 620, 403402); the King is shown wearing armour with a lace stock, a red, ermine-lined mantle over his right shoulder and around his waist, and the riband of the Order of the Garter; long powdered wig on his head.
