The Real McCoy

@GuyKawasaki blogged about the expression, “the real McCoy” and cited a Scottish origin. While that may be true, I know of another.

I believe the expression also comes from the Deep South, where I grew up. McCoy vases were popular in the 1900s and were available in many “art deco” colors, like turquoise. Copies and knock offs were made, but they didn’t have the real company stamp on the bottom.
