The Old Man of the Border

 There was a Old Man of the Border,

Who lived in the utmost disorder;

He dance with his cat, and made tea in his hat,

Which vexed all the folks on the Border.

Edward Lear

'The Old Man of the Border' a rough drawing and a final illustration by JVL in 

The Nonsense Verse of Edward Lear, Jonathan Cape, 1984 and reissued in 2012, page 37.

You can see (from a note on the rough drawing) that the final illustration, from rough drawing to finished artwork, took 7 hours and 27 minutes to complete.
