I don't recall seeing those old ads!
They were easy to miss.
Always a few pages from the back.
Where the magazine seemed to die, ie past the pages of 'WNW' review of devotional recordings - beyond which you would not venture unless you wanted the ham column, the end of an article that did not fit or wanted to know if your posted Q&A was answered!
Ads always intrigued me as a kid (who remains appreciative of the mystery donor who left a stack of old EAs in the garage one day).
Oh and thanks for your thanks - knew you'd like it!
