A long time ago, Bill S. said that thie was available through various traders:

"The Private Life Of A Sewer Worker" (2/13/54) Robert Q. Lewis and Art Carney do a take off on Edward Murrow's at-home interview show Person to Person, giving TV audiences their first view of Ed Norton's apartment.

I think I remember seeing a tape trader's website and he (or she) said that they had it. I forgot the website's and the person's name.

I think when I made that list you're referring to, I accidentally put two stars (signifying that it was available to us) when I should have only put one. In other words, it's known to exist, but I haven't come across it myself. It is listed on the Paley Center's website though, so technically it is "out there."

Thank you. Maybe someday this sketch will be made more readily available.
