How does Roger Lowenstein use imagery in Buffett: The Making of an American Capitalist?

Examples of Imagery:

This ability of Buffett to cut through the clutter suggests a certain genius. Buffett focused so exquisitely on his object, and his simplicity was a counterpart to that genius. He recognized that layers of added executives—though each might be bright, earnest, well-intentioned, etc.—would blur his focus...He did not like protracted decision-making or drawn-out and contentious bargaining. His negotiating style was to seek or propose offers on a take-it-or-leave-it basis. And once he made a decision he did not reverse it.

What was most unusual about the young salesman (Buffett) was his appetite for research. Searching for ideas, he read the heavy purple-bound Moody's manuals page for page with the zest of a small boy reading comics. And he found small gems—unwanted and very cheap cigar butts such as Kansas City Life, Genesee Valley Gas, and Western Insurance Securities, all trading at three time earnings or less. It seemed too good to be true; if the stocks were so cheap, Buffett figured, somebody out to be buying them. But slowly, it dawned on him. The somebody was him. Nobody was going to tell you that Western Insurance was a steal; you had to get there on your own.
