"The Right Honourable Chancellor of the Exchequer WILLIAM PITT First Lord of the Treasury", engraving by J. G. Huck after Karl Anton Hickel. Pitt is sitting reading The Times newspaper - you can almost imagine his breakfast things pushed aside just off the picture :)
William Pitt engraved by Charles Brome after William Owen, 1799. It seems the original painting from which this was taken was owned by Pitt's friend and colleague Henry Dundas. I wonder where it is now.
