The Thunder Clap, George Forster, 1742, British Museum.
As in Samuel Lyne's Bob the Political Ballance Master, Forster takes aim at the Walpole administration with a political cartoon that skewers them on their failure to protect oceanic trade. Only in this piece, Forster accompanies it with a lengthy diatribe in text below.
A master and sailor hold up a painting of a warships with their sails furled or turned away, and a slim privateer sloop crowded with men interrupting the frame. Pointing to the "Spaniard," a sailor (possibly a master) states "O such a powerful fleet : and yet -"
He wears a reversed cocked hat, bob wig, frock coat with open mariner's cuffs, a short neck cloth tied close, and breeches.
Just to be sure we don't miss his meaning, Forster has attached a short diddy to the bottom of the painting:
And see de little Privateer o.
Who on our Coats its Course doth steer o
And dis widout ought dread or fear o
par, par, par, &c.
