It’s been my experience that there are a handful of special objects in the world that have developed cachet or “mojo” and are emotionally appealing to people in various fields. Some of these unique items engage our interest because they’re otherwise unassuming objects which have become associated with unusual people or events. I think of the track shoes Roger Bannister wore on May 6, 1954 when he ran the world’s first sub-4 minute mile. I think of “Brownie” and “Blackie,” two of Eric Clapton’s Fender Stratocasters. The console Sam Phillips used in Sun Studios to record Elvis Presley, Johnny Cash, Jerry Lee Lewis, Carl Perkins, and Roy Orbison must drip with “mojo,” as does Pete Seeger’s banjo, no doubt.
