Sir Joshua Reynolds
"What do you ask for this sketch?" said Sir Joshua to
an old picture-dealer, whose portfolio he was looking over. "Twenty
guineas, your honour." "Twenty pence, I suppose you mean?" "No, sir; it is
true I would have taken twenty pence for it this morning, but if _you_
think it worth looking at, all the world will think it worth buying." Sir
Joshua ordered him to send the sketch home, and gave him the money.
