The photograph above is Big Mic on opening day November 14, 1948.
The following photographs of Big Mic show its poor condition. This is how the microphone looked when I sent it to Clarence Kane during the Fall of 2002.
Below are two photographs of the RCA 77D microphone from around 1950.
The photographs below show the extremely poor condition of the 77D on the day they were sent to Mr. Kane.
