"This is an excerpt from a recording I found on an old wire spool (pre magnetic tape recording medium). On April 23rd, 1950, a New Jersey man by the name of Fred Weber was setting his wire recorder up to record a phone conversation, and to test the signal he called the local Time Bureau. On the surface this would appear to be a rather mundane recording, but it isn't until you hear the time lady sneeze at 1:43 that you realize - this is a LIVE person reading off the time in 15 second intervals!"
