A spencer & a thread-paper [graphic].

"Two men in back view walk arm-in-arm, one (left) is short and fat, the other tall and thin. The former wears a short coat or spencer over his tail-coat, with wrinkled top-boots and a round hat, and carries a riding-switch. His hair is in a short queue with projecting side-pieces. The other wears a cylindrical hat with brim curled up at the sides, a coat reaching almost to his ankles with five capes forming a point in the centre of the back, with shoes tied with strings. He carries a bludgeon. The shoulders of both men are frosted with powder, see BMSat 8190. There is a landscape background. The spencer was a short double-breasted overcoat without tails called after George John Spencer, 2nd Earl Spencer (1758-1834), who is probably here caricatured.
