This was won on eBay 31 October 2003.
The 4-pack cost $4.49 and was
shipped from Pittsburgh, Pennsylvania.

I looked up patent number
3,057,467 on the US Patent Web site and
discovered within seconds that
Ross R. Williams holds the patent.
He originally filed in 1952
and was approved in 1962. Ten
years Mr. Williams had to wait.
Wonder why the delay

This proves once again that the Web is magic crap.
