Here's another one -
http://www.ebay.com/itm/1951-Los-Ang.../332119843134?
Advertised as being from April 15, 1951, but Johnny Sain being listed dates the program to no earlier than August 29, 1951.
Not to mention that Mantle is listed as #7.
I sent the seller a polite note, we'll see what happens next.
