Myneer Nic Frog's Lamentation, or Dutch Milk a fine Relish to English Sailors, W. Wells, 1781, National Maritime Museum.
The Dutch and the British, each personified, face off over a cow's milk. I'm having a lot of trouble understanding what precisely is going on here, but the British sailor is clearly making away with the milk while ships in the background trade broadsides. This cartoon is wonderfully colorful and detailed, and gives us a lot to talk about.
The tar wears a black round hat with a wide brim that is just barely turned up on each side. His neckcloth is yellow with red stripes. Our sailor's white lined blue jacket ends at the top of the thigh, is double breasted with slash cuffs, and no pockets. His waistcoat is red and triple breasted with brass buttons. The broad fall fly of his slops are wonderfully detailed, and the slops themselves are striped with red vertical stripes! This is very unusual indeed. Beneath this is a pair of white stockings, and pointed toe shoes with rectangular buckles.
