The gradual abolition off the slave trade or leaving of sugar by degrees, engraving 1792, George III sitting at a table with the Queen and two of his daughters, and the Queen's Keeper of the Robes, Juliana Elizabeth Schwellenbergen holding a bottle of Brandy, discussing the use of sugar in moderation. Princess Elizabeth states that of late I have been very moderate. But I must have a bit now & then, while her sister would rather want alltogether [sic] than have a small Piece. The title is a play on the words of and off, the abolition of the slave trade or leaving off sugar by degrees.
