Thanks Ankesh for sharing Gary Halbert's famous "
Nancy letter"... As far as I know, the letter you posted in your post was the only (or certainly one of the few) direct mail pieces which was mailed to a "phone book list"... They just got the names out of the phone book! (Matched to the customer's surname...)
Here is another famous one of Gary's ads... His personal ad. I believe he ran this as a full-page ad in an L.A. newspaper...
You can see it here...
