Not a strange Christmas card (and not “Victorian”, either), @weirdchristmas, but a satirical cartoon from February 1805!
The title is The Plumb-pudding in danger, or, State Epicures taking un Petit Souper by the famous cartoonist James Gillray.
Depicted are to the left, in the characteristically red uniform coat associated with the British army, Prime Minister William Pitt (the younger), and to the right, in a blue uniform coat, Emperor Napoleon Bonaparte.
This image seems to be cropped, as the original is wider, depicting the back of the chairs of Pitt and Napoleon decorated with the heraldic animals representing their respective country, an attribution to Gillray in the upper left corner and in addition to this, the title to the right has been cut off.
Between Pitt and Napoleon, on a gold serving platter on the table stands an overlarge, steaming pudding, which both men are carving pieces off of. Pitt appears to use a large carving knife, wereas Napoleon uses his sword. Their golden plates are yet empty as they cut the pudding into pieces.
The pudding displays latitudes and longitudes as well as a stylised map. Napoleon cuts a smaller slice off the pudding than Pitt does, who cuts off half the pudding. Only a very small strip of it, depicting the British Isles, is left intact between the cuts the two men make. The phrases “Atlantic Ocean” and “Europe” show which portion of the world the men each claim for their country.
Gillray takes aim at the political situation in early 1805; while Britain, invested in its colonial ventures, claims half the world (labelled “Atlantic Ocean”) for itself and also thinks of itself as being the dominant sea power of the time, it allows Napoleon to strike close to home with only the channel separating Britain and France while Napoleon, then newly-crowned Emperor, aims to bring the entirety of continental Europe (labelled “Europe” on the pudding globe) under French control.
Dating to February 1805, the cartoon is by no means intended to be related to Christmas; pudding was, during the Georgian era, not a highly seasonally specific dish associated with a single holiday yet, and eaten throughout the year.
Have I forgotten anything, @pitt-able?
