I Wonder...
...If Crosley's claim to fame was the shelves themselves, or the name "Shelvador?"
There have been certain brand names that are so perfect that they stick in the public's mind forever, and make competing companies wish to Heaven they'd thought of them first. Chrysler's "Town and Country" name for woodie convertibles and wagons was one. The management of the Pennsylvania Railroad had one of the finest trains in the world, running between New York and Chicago, called the Broadway Limited. Unfortunately for the Pennsy, rival New York Central called their train the Twentieth Century Limited, a name so good that Pennsy execs blamed it for the Broadway's perpetual red ink.
Does anyone know if Crosley actually had a patent on door shelves, or if the name was so memorable that people got it into their heads that the only way to get the feature was to buy a Crosley?
